After the ore is sorted and comprehensively treated, its main useful components are rich in concentrate, while other residual materials are called tailings. The content of the main useful components in the tailings is called the tailings grade. It is an important parameter for selecting an economical and reasonable beneficiation program to evaluate the selectivity of ore. What is the ore grade α? Ore grade refers to the content of useful components or useful minerals per unit volume or unit weight of ore. Generally expressed in weight percent (such as iron , copper , lead , zinc, etc.), some in grams per ton (such as gold , silver, etc.), and some in grams per cubic meter (such as gold, etc.), Some are expressed in grams per liter (such as iodine , bromine and other chemical raw materials). The mineral product position is the main indicator for measuring the economic value of the deposit. What is the concentrate grade β? After the ore has been sorted by an economical and rational beneficiation process, its main useful components are enriched and become concentrates, which are the final products of the concentrator. The content of the main useful components in the concentrate is called the concentrate grade. Some concentrate grades are expressed in weight percent (such as copper, copper, zinc, etc.), and some are expressed in weight ratio (such as gold ore in grams per ton). It is an indicator reflecting the quality of concentrates and a parameter for the process of mineral processing. What is industrial grade? Industrial grade is a component of the mineral industry requirements and is the main indicator for calculating mineral reserves. Refers to the industry's lowest average grade of a single project (or mine or ore body). It is the lower limit for calculating the possible reserves (inside the table). The determination of industrial grade is closely related to the characteristics of the deposit, the mining conditions, the type of ore and the performance of the selection and processing technology. The meaning of this term refers to the lowest industrial grade or the lowest recoverable grade, which has been used less to avoid confusion. What is the cut-off grade? The cut-off grade is a component of the mineral industry requirements and is the main indicator for calculating mineral reserves. Refers to the lowest grade of mineral and non-mineral boundaries, ie the lowest grade of useful components in a single ore sample when delineating ore bodies. The grade of the boundary is determined according to the scale of the deposit, the conditions of mining and processing technology (optional), the grade of ore and the content of associated elements. It is the main basis for delineating ore bodies. In foreign countries, there is no industrial grade requirement, and the boundary grade is the sole grade basis for delineating ore bodies.
