Ore Beneficiation

Crushing and screening is typically the first step of iron ore beneficiation processes In most ores including iron ore valuable minerals are usually intergrown with gangue minerals so the minerals need to be separated in order to be liberated This screening is an essential step prior to their separation into ore product and waste rock

Crusher

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.

Agglomeration Drums in the Heap Leaching Process

Heap leaching a process by which metals such as gold and copper are recovered from ore has long been a method of choice in ore beneficiation with applications growing all the time. While this process has proven to be efficient often chosen for its cost effectiveness the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum.
