Mill reject handling system. Magaldi. Magaldi Group

Discharged from coal mills, the rejects are collected in pyrite boxes for temporary storage. The material is extracted from the pyrite boxes by MRS® extracting conveyors or vibrating feeders and then dosed onto the main MRS® conveyor, which collects the rejects produced by all the coal mills. Downstream the main MRS® conveyor, the rejects can be discharged onto a movable container or into a storage silo.

A method for generating uniform size-segregated pyrite

10/10/2007 Pyrite powders are usually prepared by grinding a homogenous, massive pyrite sample using an agate mortar and pestle [10, 16–18] or a mixer mill . To achieve a specific size range of material for experiments, samples are either dry sieved [ 17,18 ], wet sieved [ 16 ], or both [ 11 ].

Pyrite Tailings Recovery by Flotation

Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings can be treated to yield pyrite concentrates that are a suitable source of sulphur dioxide for the manufacture of sulphuric acid. Such concentrates must normally contain at least 48% sulphur.

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.. The extraction of minerals from ore can be done two ways: placer mining, which uses water
