Mineral Processing and Ore Dressing

Jun 02, 2016  Mineral Processing and Ore Dressing. Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs.Jun 02, 2016  Mineral Processing and Ore Dressing.

Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur.

Magnetic separation Method. By this method, those ores can be concentrated which either contain impurities which are magnetic or are themselves magnetic in nature. For example, the tin ore, tinstone (SnO 2) itself is non-magnetic but contains magnetic impurities such as iron tungstate (FeWO 4) and manganese tungstate (MnWO 4).Magnetic separation Method.

The crude ore from the mines contain a number of solid phases in the form of an aggregate. The valuable portion of the ore is known as mineral while the worthless portion is known as gangue. During ore dressing, the crude ore is reduced in size to a point where each mineral grain becomes essentially free so as to make separation between them.The crude ore from the mines contain a number of solid phases in the form of an aggregate.

The crude run-of-mine mineral must be processed to separate it from impurities such as mud, waste rock, or mixtures of other minerals. This procedure, called ore dressing, also serves to increase the mineral content of the ore before it is sent to the smelters. The resulting mineral is called a concentrate.The crude run-of-mine mineral must be processed to separate it from impurities such as mud, waste rock, or mixtures of other minerals.
