Yankuang Sheets Industrial Indicators

The atomic structures of strontium and strontium are the same, their geochemical properties are similar, and they coexist in nature, producing extremely complete series of similar minerals. No deposits of pure and pure strontium have been found. According to the genesis (mineralization), the antimony deposit is divided into three categories: exogenous, endogenous and metamorphic deposits. The main types of industrial deposits are granite pegmatite deposits, granite deposits, carbonate rock deposits, alkaline rock deposits, hydrothermal deposits, weathered deposits and river impact deposits. Industrial requirements for antimony ore are often based on the geological characteristics of various deposits, the technical conditions of mining, the composite composition of ore, the treatment process, and the geo-economic characteristics of the deposit. Usually tantalum niobium placer claim containing tantalum and niobium mineral greater than 50g / m ^3, of the original deposit containing _{(Ta + Nb) 2 O 5} > 0.02%, of the carbonate rock in pyrochlore claim Nb ₂ O ₅ at 0.1% to 0.5%, or higher. The grade of industrial deposits in China is shown in Table 1.

It should be pointed out that although cockroaches are symbiotic in minerals, the reserves of natural cockroaches are far more numerous. Some of the world's largest deposits are actually strontium deposits, with a ratio of strontium and barium in the ore of 400:1, the world's largest Araxa bismuth mine in Brazil, the Niobic bismuth mine in Canada, and China's The Baotou Bayan Obo mine is actually a “pure” antimony ore, and the traces contained in it are virtually impossible to recover.
