POTENTIAL CHANGES IN THE PHYSICAL BENEFICIATION PROCESSES THAT CAN IMPROVE THE RECOVERY GRADE OR COSTS FOR THE PLATINUM GROUP METALS J. Engelbrecht Multotec (Pty) Ltd Abstract Understanding the deportment of minerals in size fractions has already led to improvements in the flow sheets for platinum minerals beneficiation. There are, however, more .

Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an orewater pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineralwaterair froth.

Mineral processing operations generally follow beneficiation and include techniques that often change the chemical composition the physical structure of the ore or mineral. Examples of mineral processing techniques include smelting, electrolytic refining, and acid attack or digestion. Mineral processing waste streams typically bear little or no resemblance to the materials that entered the ...

The flotation method is based on the difference in the physical and chemical properties of the mineral surface, processed by the flotation agent, and the mineral is selectively attached to the bubbles to achieve the purpose of separation. The beneficiation of nonferrous metal ores, such as copper, lead, zinc, sulfur, molybdenum, etc., is mainly treated by flotation; some ferrous metals, rare ...

copper concentrate was increased from % to %, iron recovery of magnetic separation was increased significantly from % to %, and other evaluation indexes were changed slightly, in comparison with unmodified copper slag. Moreover, matte and magnetite grains in the modified slag aggregated together and grew obviously to the mean size of over 50 m, resulting in an improvement ...

As a result of the physical and chemical actions, the copper value rises to the surface of the flotation unit as froth. The material remaining on the bottom of the flotation tank ("gangue") is partially dewatered and then discharged to tailing ponds for disposal. The concentrate resulting from the flotation circuit contains approximately 30 percent copper and, in some instances, may also ...

physical rather than chemical principles. To be more specific, let us take the example of a copper ore whose grade, or copper content, is only 1% by weight. Let us assume that the sole copper mineral species in this ore be chalcopyrite, which is one of the most popular copper minerals found in copper ores in our planet.

The physicalmechanical mineral beneficiation which removes a large portion of the waste material is much simpler and less expensive to do than the pyrometallurgical or hydrometallurgical processes. Economic Benefits Some of the economic benefits of beneficiation preceding a pyrometallurgical treatment would be: (a) lower transportation and handling costs; (b) reduction in smelting costs as ...
