Ore English: mineral

Ore refers to the mined down from the mines containing some valuable minerals in the stone, ore after crushing, grinding and other step-by-step processing can be applied in the metal mines, metallurgical industry, chemical industry, construction industry, railway (public) road construction units, cement industry and gravel industry and other engineering fields.

The useful components in the ore (elements or minerals) of the unit content known as the ore grade, gold, platinum and other precious metal ores with grams / ton, other ores commonly used percentage of the said, commonly used to measure the value of the ore grade, but the same effective component of the ore in the vein (ore in the useless minerals or minerals that can not be utilized in the useful components of the content of the minerals are very little) of the composition and the number of harmful impurities also affect the The value of the ore.

Composition of Ore:

Ore generally consists of ore minerals and vein minerals. Ore minerals are metallic or non-metallic minerals in the ore that can be utilized, also known as useful minerals. Such as chromite in chrome ore, chalcopyrite, porphyry, chalcopyrite and malachite in copper ore, and asbestos in asbestos ore. Vein minerals are those minerals that are associated with ore minerals and cannot be utilized for the time being, also known as useless minerals.

For example, olivine and pyroxene in chrome ore, quartz, sericite and chlorite in copper ore, and dolomite and calcite in asbestos ore. Vein minerals are mainly non-metallic minerals, but also includes some metal minerals, such as copper ore containing a very small amount of galena, sphalerite, due to the lack of comprehensive utilization value, also known as vein minerals.

The ore contains ore minerals and vein minerals in the proportion of the ratio, with different metal ores and different. In the same kind of ore also with the ore rich and poor grade different and different. In many metal ores, the amount of vein minerals is often far more than the amount of ore minerals. Therefore, before smelting, the ore must be beneficiation, discard most of the useless material before smelting.
