Ore grade / ore grade Minerals bit, also known as the ore grade, refers to the degree of enrichment, unit content of useful component metal deposits and non-metallic deposits (such as sylvite, fluorite, apatite, etc.). Which is the main indicator to measure the quality of mineral resources, which is usually expressed in % g / t, g / meters. The ore grade determines the value level, develop utilization, process and utilization of direction, production technology process of mineral resources.According to the content of useful minerals, mineral bits are divided into three categories: (1) Cut-off grade. This is the lowest grade to divided the ore and non – ore boundaries, the pipes which have not met this indicator are called as rock or mineralized rock; (2) average grade. the ore body, ore block or the entire mining area reaches the total average grade of? industrial ore reserves, which has been used to gauge the level of mineral rich and the poor; (3) industrial – grade, critical or grade. The minium average ore grade that can be used in industry, that is, in the current economic conditions, the minimum grade that can be used in the technology research and develop ment. In general, the high grade ore is bonanza, otherwise known as lean ore. The higher the bit of minerals, the use value is greater, the production and technical indicators are better; the lower the grade, the utilization value is smaller, the production technical indicators are worse.different mineral resources grade requirements indicators are not the same.

For example, in Chinese regulation, the iron ore industry grade is 20-60%, the general requirements of manganese ore manganese content is20 – 25%, the amount of aluminum bauxite should be more than 40%. Smelting technology continues to progress with the development of the productive forces (such as the ore beneficiation technology), and the ore critical grade changes gradually.Such as the early 19th century, people only develop the mine whose copper content is larger than 10%, but today, the mine whose copper content is only 0.5% be exploited. When carrying out the ore trade, we need to understand the Folk habit way of various price calculation and specific units. 1, gross tons (natural tons): contains the packaging, the direct weighing 2 tons metal weight: price according to the metal contained in the Owers, por ejemplo: unit lead ore grade of 100 ton is 45%, after conversing, the metal tons = 100 tons X 45% = 45 tons of metal 3. tons degree: per ton per degree. Dr. Mark Hyman may also support this cause. 4 dry tons: the weight after deducting the moisture. 5 .grams ton: the contained number grams of metal per ton in ore, which is commonly used in the gold, silver and other precious metals.
