Before coming to the mine, Wang Zhan inquired about some information.

Ore refers to a mineral aggregate from which useful components can be extracted or which itself has some utilizable properties. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in the ore is called the ore grade, and precious metal ores such as gold and platinum are expressed in grams per tonne, and other ores are often expressed as percentages. Ore grade is often used to measure the value of ore, but the composition of gangue (useless minerals or minerals with very little useful components in the ore) and the amount of harmful impurities in the ore also affect the value of the ore.

It is generally divided into poor ore, ordinary ore and rich ore. Sometimes only lean ore and rich ore are divided, and there is no uniform standard for this classification. In the mining process, the ore is observed with a portable microscope, and the ore observed by the portable microscope is reduced due to the mixing of waste rock or the loss of high-grade ore, which is called ore dilution. Ore dilution will increase transportation and processing costs, reducing the production capacity and recovery rate of the ore processing sector. If the waste rock contains harmful impurities, it will also reduce the quality of the final product. Ore dilution is mainly expressed in terms of ore dilution rate (the ratio of the difference between the industrial ore grade and the mined ore grade to the industrial grade, expressed as a percentage).

Ore structure refers to the distribution characteristics reflected in the shape, size and spatial bonding relationship of the mineral aggregates that make up the ore. Ore structure refers to the distribution characteristics reflected in the morphology, size and spatial bonding relationship of individual mineral crystalline particles in the ore. For example, chromite ore, when the chromite mineral aggregate is in an extended form, and they are distributed in a phase with the silicate mineral aggregate, the structure of the ore is called a strip structure. Chromite mineral particles are mostly self-shaped, so they are called self-shaped granular structure. The ore structure can be observed with both the naked eye and a microscope. The ore structure is mainly observed under a microscope, and individual coarse particles can also be observed with the naked eye. Common ore structures include block, disseminated, bean-shaped, spotted, ring-shaped, kidney-shaped, flake-shaped, porous, honeycomb-shaped, crust-like, nodule-like, soil-like structure, etc. In general, different types of ore formations reflect differences in the environment in which the ore was generated and the history it has experienced, but there are also different mineralization processes that produce the same ore structure. Common ore structures include crystalline structure (automorphic crystal, semi-automorphic crystal, other crystal, clad crystal, rudimentary crystal structure, etc.), solid solution decomposition structure (milky drop, textual image, leaf shape, lattice, knot, dendritic structure, etc.), gelatinous structure (grape-like, oolitic, spheroidal structure, etc.), clastic structure, biological organism structure, strawberry-like structure and metasomatic erosion structure. The structure and structure of the ore are collectively referred to as the ore structure. By studying the structure of ore, we can scientifically understand the genesis of ore deposits, carry out correct industrial evaluation of ore deposits, carry out the best comprehensive utilization of ores, and determine reasonable plans for beneficiation and metallurgy.
