What are the mineral industry indicators and what are commonly used?
Mineral industry indicators are indicators used to measure whether a geological body can be used as a deposit, ore body or ore, which is the minimum required for current industrial levels. Industrial indicators are commonly used in the following categories:
1. Boundary grade refers to the dividing grade between ore and waste rock. If the useful component is lower than the cut-off grade, it is treated as waste rock.
2. Industrial grade The lowest average grade of useful components of ore bodies or nuggets that are commercially available under current industrial and industrial conditions and economic conditions.
Third, the minimum recoverable thickness is the lowest thickness that the ore body can be mined under current mining technology and economic conditions.
Fourth, the stone removal thickness refers to the minimum thickness of the mineralized interlayer in the ore should be rejected. Rocks smaller than this thickness are incorporated into the ore body to calculate reserves.
5. The lowest percentage of the meter is the product of the minimum recoverable thickness of the ore body and the lowest recoverable grade. Some ore body, especially some of Precious metals, although sometimes less than the minimum thickness can be taken, but its useful components than the lowest grade of industrial grade is much higher, even though a certain thickness of the surrounding rock mining is still economically reasonable. At this time, it is necessary to comprehensively consider the influence of the thickness and grade of the ore body on the mining value of the deposit. This indicator is not suitable for thick and poor ore bodies.
