Effects of iron ore tailings on the compressive strength

In light of this, there is an urgent need for low-cost materials such as fine aggregate in UHPC production. Iron ore tailings (IOT) are mining waste obtained during the beneficiation process to concentrate iron ore,. The discharge capacity of tailings in China increases every year, accounting for more than 50% of the world's tailings discharge.get price

Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.get price
