(1) Minerals - Natural elements and natural compounds formed by geological processes in the earth's crust are collectively referred to as minerals.
(2) Ore - Those who encountered mineral aggregates in the crust, in the current level of technical and economic conditions, to extract an industrial scale of the national economy must be called metal ore or mineral products.
(3) Ore body - The aggregate of ore is called the ore body. (An ore body is an independent geological body with a certain geometric shape, a certain spatial position, etc.).
(4) Mineral deposits - deposits are the general term for ore bodies. (For a mine, a deposit consists of one or several ore bodies, which can be divided into industrial deposits and non-industrial deposits).
1 Industrial deposits – Under current technical and economic conditions, mineral deposits that meet mining and utilization requirements are called industrial deposits.
2 non-industrial deposits - in contrast to the above, called non-industrial deposits.
(5) Surrounding rock—The rock around the ore body is called surrounding rock.
1 The surrounding rock of the upper plate refers to the surrounding rock of the upper part of the ore body.
2 The surrounding rock of the lower plate refers to the surrounding rock of the lower part of the ore body.
(6) Stones - The rock caught in the ore body is called a stone.
(7) Concept of waste rock The surrounding rock or stone collected during the mining process is generally called waste rock. (Or waste rock is: the surrounding rock around the deposit is rock-filled, contains no useful ingredients at all, or is too low in content. It is currently not suitable for mining ore as waste rock).
[Note] It should be pointed out that the concept of ore and waste rock is relative. It has a relationship with the social system of a country, the level of scientific and technological development of a country, the resources already in place, and the demand for certain metals. . For example, tin and copper , in the past tin grade reached 0.8%, only the ore can be mined, and now the tin grade as long as 0.2 to 0.3%, as the ore mining, the past copper grade only reached 1.0%, only mining, and now It can be used as ore mining when it reaches 0.4-0.6%. In the past, waste rock, but now it has become a mine that can be mined. (Gold grade is 8 ~ 10 g / ton is rich mine)
