processing and production lines of hard rock tin mining
Rock Crushing Process in Mining
The gap opening of the primary's mantle is very important not only to the production of the primary but also to the next stage of size reduction. As the ore becomes smaller it becomes harder to crush. This is because there aren't the same amount of fracture lines in small rock as there are in large rock.

Limestone | Minerals Education Coalition
Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the is either limestone or dolomite.

Tailings Wikipedia
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
