Dense Medium Separation
Pre-concentration has been practiced in industry for many years, and is gaining greater interest as the industry copes with processing lower grade, more difficult ores, typically requiring finer grind sizes and higher energy costs. The benefits of pre-concentration are as follows: • Lower mining costs: allows non-selective mining;
Mineral Concentration Plant and Milling – Minera San ...
The concentration of zinc, lead and silver in the mineralized rock extracted from the Jayula and Tesorera pits in the San Cristóbal mine is very low; it is therefore necessary to have the material undergo a process designed to increase the content of these elements and thus obtain products with a commercial value. In this sense, the concentration plant was designed to obtain two enriched ...

Mineral processing - Mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic ...
Namakwa Sands, South Africa – Tronox
The open-pit mine and concentration plants are situated at Brand-se-Baai, 385km north of Cape Town. Here the ore is mined and processed at the primary concentration plants to produce a mineral concentrate. It undergoes further processing at the secondary concentration plant to yield a magnetic and non-magnetic stream.
Ore Sorting & Pre-Concentration
· Ore Sorting helps the economics of mining when ore becomes diluted by country rock because of narrow slopes or because of weak wall rock, or when it naturally contains barren material which is distinguishable from the ore, sorting and rejecting the worthless rock may be economical. This is done in a casual manner at some small mines and on a large scale at others, as was the case at …
