Is it difficult to apply for the latest Estonian license in 2020?

Estonia is a member of the European Union and one of the three Baltic countries. The government has open supervision of cryptocurrency. and a positive attitude, it is a popular area for cryptocurrency activities.

It is the first country in the world to issue tokens ICO in the name of the country.

As a true digital currency license, the Estonian dual license includes a digital currency transaction license and a wallet license. The business scope can reflect digital currency transactions, including blockchain technology development, exchange currency, legal currency, Contracts, wallets, etc. permissions. For the project side, this license can be said to be very practical. Therefore, Estonian MTR has been sought after by major project parties due to its ultra-high gold content.

According to the OECD, Estonia has one of the most competitive tax policies in the world. No profit tax applies in Estonia. Bitcoins and altcoins are not subject to VAT.

Documents required to apply for an Estonian MTR license:

1. The company name needs to be verified. It cannot be too long and cannot involve trademark words.

2. Director information (ID card) and English resume (financial related).

3. Original certificate of no criminal record of the director

4. Notarized POA signature document

5. Registration time: about 45 working days

It becomes more difficult to apply in Estonia, and you will be randomly checked to answer questions. The new policy stipulates an increase in actual office work (including already processed). The office address needs to be leased on a long-term basis and requires staff. Do you think Estonian license plates are troublesome? In fact, these are not problems – they can all be solved. But it will indeed become more and more difficult to apply in Estonia in the future.

Estonia application process; first register a local company and then apply for a license

Documents required for license application: Provide criminal certificate + passport + address proof (to be notarized)

I would like to repeat the question about being randomly checked. The probability of being randomly checked is very high, so you must understand English (answers must be in English or Estonian) or use other methods to discuss in detail.

Follow-up costs: Company annual review + maintenance fee/year

㈡ Laterite bauxite

Laterite bauxite It is the most important type of bauxite in the world and is mainly distributed in the tropical rainforest areas of South America, West Africa, Southeast Asia, India, Australia and other places within the 30° north and south latitude.

Northern South America metallogenic belt: mainly distributed in the Guyana Shield and the northern coastal plain of Guyana, Suriname and French Guiana, the Amazon River Basin and the northern part of the Brazilian Shield.

The West African mineralization belt: spreads across the West African plate, mainly located in Guinea, Cameroon, Mali, Ghana and other countries.

Indian mineralization belt: located in East Ghats of the Indian Peninsula.

Southeast Asian metallogenic belt: mainly distributed in Vietnam, Laos, Cambodia,Indonesia, Malaysia and other countries.

Australian metallogenic belt: mainly distributed in northern and western Australia.

The bauxite resource reserves in the above mineralization belts account for 96% of laterite-type bauxite reserves (Badosi, 1994). The mineralization era is dominated by the Cenozoic.

Laterite-type bauxite is generally produced in landform environments such as plateaus, domes, elongated single-sided mountains, mountain slopes, flat coastal quasi-plains and sedimentary flats, and small depressions on flat quasi-plains. . Plateau platforms are the most important. Bauxite minerals in India, Guinea, Cameroon, Brazil, Guyana, Australia, Vietnam, Laos and other places are produced under this landform environment. These platforms are generally remnants of ancient planations in geological history.

Most of the laterite-type bauxite (reserves account for 95% of laterite-type bauxite) is located on the surface and is not covered by new sediments. The parent rocks are mainly quartz-free rocks and rocks with little quartz. Only a small amount of mineral deposits are formed by the weathering of granite, rhyolite and sandstone with high quartz content.

The morphology of the ore body is mostly layered and layer-like. Most mining area profiles can be divided into four layers: top soil layer, iron hardened layer, bauxite layer, and residual layer. The induration layer is generally bright red, dark red, or brown, with a nodular, lumpy, and colloidal structure. It is hard and has a high iron content. The bauxite layer is generally yellow-brown, partially red or reddish-brown, and its main structures include nodules, lumps, beans, etc. The residual layer is generally light-colored or variegated, soft and soil-like, and mostly retains the original rock structure.

The average mass fraction of Al2O3 in the ore is generally 40% to 45%, the mass fraction of SiO2 is 4% to 8%, and the mass fraction of Fe2O3 is generally 10% to 25%. In some mining areas, deirification occurs and the iron content is low. Gibbsite is the main ore mineral, followed by boehmite, and diaspore is rare. Kaolinite is the most common silicate mineral.

The bauxite deposit in Basong County, Champasak Province, Laos is a Quaternary laterite-type bauxite and has the typical geological characteristics of laterite-type bauxite.

The deposit is located on the Bolofing Plateau in Champasak Province in southern Laos. The geographical coordinates are 106°33′36″~106°39′15″ east longitude and 15°00′00″~15°07′ north latitude. 48″. It belongs to a tropical rainforest climate zone with dense vegetation and difficult access. The rainy season is from May to October every year, with abundant rainfall. The surface of the plateau is covered with Paleogene, Neogene and Quaternary basalts. Laterite-type bauxite is formed by the weathering of basalt and covers the basalt. The basalt is partially weathered and the bauxite covers the Mesozoic sandy conglomerate.

The terrain height difference within the mining area is small. The height difference between the highest and lowest parts of the mining area is about 100m. The height difference between highlands and adjacent valleys is generally less than 50m. Bauxite ore bodies appear in higher locations such as ridges and hills. , the thickness of the ore body becomes smaller and the grade becomes lower towards both sides. The bedrock is exposed in the valley, and no ore bodies appear.

The laterite weathered layer in the mining area can be divided into four layers from bottom to top: the bottom is a variegated clay layer, the middle is a bauxite layer, and the upper part is an iron layer.The surface is soil and humus layer.

The thickness of the clay layer at the bottom is 0~8.13m, with an average of 2.05m. It is yellow, red, white and other variegated colors. The main mineral components are clay, iron and a small amount of bauxite nodules. Some residues can be seen locally. There are basalt fragments and quartz sand and gravel on the sandy conglomerate; the middle bauxite layer is 0~11.62m thick, with an average of 4.55m. It is generally yellow-brown and partially reddish-brown, and the ore is produced in the form of nodules of varying sizes. In soft red soil. The lower part is tubular and sheet-like bauxite with a diameter of 1 to 3 cm, containing about 30% to 40% nodules; nodular, bean-shaped, and kidney-shaped bauxite appears upward, and the largest nodules can reach 15 cm in diameter. They are connected to each other into blocks with a diameter of 1~2m, containing 50%~70% nodules. The upper iron layer is 0.40~6.50m thick. Reddish brown and red iron nodules and clumps are distributed in the laterite, and the nodule content can reach 60%~80%. In most areas of the mining area, the Fe2O3 mass fraction of iron nodules can reach up to 60.45%, and most samples meet the cut-off grade requirements for hematite ore.

The ore is laterite-type gibbsite ore, which is yellow-brown, reddish-brown, purple-red, etc. The main mineral is gibbsite, followed by kaolinite, goethite, hematite, anatase, etc. The ore structure has typical structural characteristics of colloidal origin. There are mainly nodular, bean-shaped, flaky, tubular and other structures, which are formed by the periodic precipitation and aggregation of mineral components such as diaspore, hematite, and limonite in red soil. Nodules and pisolite appear in the upper part of the ore body, and are locally interconnected to form a massive structure. Bauxite appears in the lower part of the ore body with flaky and tubular structures. The diameter of the nodules becomes smaller and the number of nodules decreases. The ore structure is formed by surface weathering and sedimentation, and mainly has layered, cap-shaped, and shell-shaped structures.

The main chemical components of bauxite ore are Al2O3, SiO2, Fe2O3, TiO2, etc. (Table 4.8), the mass fraction of Al2O3 is 28.04%~55.79%, the arithmetic mean is 42.07%; the mass fraction of SiO2 is 0.94%~ 20.22%, average 6.31%; Fe2O3 mass fraction 7.75%~45.50%, average 23.55%; TiO2 mass fraction 1.35%~7.98%, average 3.07%.

Table 4.8 Chemical composition characteristics of Laos bauxite rock ore wB/%

Relevant analysis shows that the Al2O3 mass fraction and SiO2 mass in bauxite Fraction, Fe2O3 mass fraction, and TiO2 mass fraction all have an obvious inverse proportional relationship. The correlation coefficient between Al2O3 and SiO2 of 1595 bauxite samples is -0.37, the correlation coefficient with Fe2O3 is -0.92, and the correlation coefficient with TiO2 is -0.48. Compared with iron ore, bauxite has a higher titanium content, and high-grade bauxite has a higher titanium content.

It is speculated that during the formation of bauxite, strong lateritization led to the migration of aluminum in the upper iron layer, and the iron oxideIt is most stable under oxidation conditions, and remains to form an iron layer. Aluminum migrates downward to increase the Al2O3 mass fraction of the aluminum layer. Due to the stable nature of TiO2, it shows the characteristics of a low titanium ratio in the iron layer and a negative correlation between bauxite Al2O3 and SiO2.
