| Metallic elements or minerals in the content of useful components. It's that different, the majority of metal ore, such as iron, copper, lead, zinc ore, which is based on the weight of the metal elements expressed as a percentage; some metal ore grade is based on the oxides (such as tungsten trioxide, the five vanadium oxide, etc.) expressed as a percentage of the weight; the majority of non-metallic mineral raw materials are useful minerals or compounds in which the weight is expressed as a percentage, such as potash, alunite; and some non-metallic minerals will depend on the |

| fossil itself, the physical, chemical properties , such as the type of crystal and precious stones; precious metal ore in g / ton, said; native to carat diamond ore / ton or mg / ton, said (1 carat = 0.2 grams); placer in grams / cubic meter or kilograms / cubic meters, said. In mineral exploration, the commonly used grade is divided into border and non-mine the lowest grade of ore boundaries. Industrial grade can mean for the current exploitation of the ore body above the minimum or average grade, industrial grade, also known as the minimum. In order to achieve this grade industrial reserves calculation. The ore minerals of different industrial-grade requirements are different, although the same minerals, but different types of ore, industrial-grade requirements there is a difference. Industrial grade of ore demand is progress with economic and technological change, in general, industrial grade depends on the following factors: the size of deposits, mining conditions, the possibility of comprehensive utilization of minerals, ores and other process conditions. |

Ore minerals in accordance with the amount of mineral content can be divided into:
① The main mineral that more content in the ores and minerals in a particular play a major role in the minerals;
② secondary minerals, ore means less content on the ore grade of the mineral can not afford to play a decisive role;
③ trace minerals, referring to the general content of the ore in small, not big on the role of ore minerals. Elements of certain characteristics of the ore minerals, trace minerals such as nickel-platinum group element minerals, although little of its content, but have a high utilization value, these trace minerals are still greater economic significance.
In the study of the mineral composition of ore, but also to distinguish between the causes of minerals (primary and secondary, and metamorphic) and the mineral characteristics of the process (easy, and the Refractory) and so on.
Ore particularly, in addition to the main group, but also associated with beneficial and harmful components of components. Useful component is associated with recyclable components or products to improve the performance
of the component. Such as iron ore are associated with manganese, vanadium, cobalt, and rare earth elements such as niobium. Harmful components of the ore have a great impact on the quality, such as iron ore in the high sulfur content will reduce the tensile strength of metal to make steel become brittle at high temperatures; phosphorus make steel more and crisp, such as in cooling.
Ore is a relative concept, with the human fossil of the new requirements of the growing raw materials and process technologies continue to improve conditions, the current can also be useless as a mineral ore minerals. Determine
the mineral and non-mining is a major factor in the requirements of the grade of ore. |
