The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
Crushed ore heap leaching involves reducing ROM ore to a predetermined optimal target size distribution, sometimes with topsizes as small as 12.5 mm (0.5 in.) or even finer through multiple stages of crushing. Crushing increases surface area and mineral liberation which, in turn, result in higher, more economic recovery. Crushed ores are …
Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.

The fact that many of the largest crushing and screening plants-which are supposedly the best-engineered-perform very differ- ently from design predictions leads to the conclusion that crushing and screening is a most fruitful area for achieving economies in …
A complete copper-nickel sulfide ore processing production line is crushing, grinding, flotation, and tailings treatment.
The ROM ore undergoes crushing and milling before the gold is dissolved using cyanide. The gold is extracted from the cyanide solution using activated carbon. The gold is removed from the activated carbon into a solution. This solution utilizing different flow sheets.
Typical comminution flow sheet for preparing small flotation feed particles from as-mined sulfide ore pieces [ 1 ]. One stage of crushing and two stages of grinding are shown.
It is a challenge to recover copper from low grade ore in an environmentally sustainable way, especially from low-grade copper sulfide resources. This paper introduces Zijinshan Mine where an integrated process was developed and applied to recover copper from low-grade copper sulfide ore and acid mine drainage (AMD).
In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum. This paper addresses the critical design parameters as well as the consideration of ore characteristics, geographical location, climatic conditions, expected …
In service since the mid-eighties and used primarily in cement production, high pressure grinding rolls are increasingly being deployed as tertiary and quaternary crushers in mineral comminution circuits, dealing with tougher ores including iron, gold, copper and diamonds.
Another major step in the crushing circuit, for bauxite ore applications and nearly all crushing applications, is the screening stage. The screening stage separates particles in the material flow by their particle size.
Low-grade iron ore received from the West Singhbhum area of Jharkhand state in India was used to develop a beneficiation flow sheet to remove alumina (Al2O3 ) and silica (SiO2 ) from the ore to get iron (Fe)-rich product for steel plants. Mineral characterization showed that the main mineral constituents present in the head sample are goethite, limonite, …
Copper production begins with acquiring raw materials like ore, concentrate, or matte. These raw materials come from mines around the world where ores containing copper sulfide minerals are extracted using open-pit mining or underground mining techniques. The ore is then crushed and heated to separate the copper from …
Although there are several ores, 80% of the world copper production comes from the ore chalcopyrite ( CuF eS2 ). The extraction of copper from chalcopyrite involves partial roasting, removal of iron and self-reduction.
Simulations indicated that a capacity increase of 12% would be achieved in the existing grinding circuit by further crushing 35% of SAG mill fresh feed. Such figures would represent yearly additions of 8.3 kt in copper and 250 kg in gold productions. Keywords: grinding; SAG; pre-processing; copper ore. 1.

Crushing is an important step in comminution that prepares the ROM ore for primary grinding and other downstream processes such as heap leach. The selection of the right crushers and crusher flow sheet is dependent on the upstream mining method and blasting characteristics and the downstream process requirements.
For beneficiation of a particular iron ore, the emphasis is normally to develop a cost-effective flow sheet incorporating necessary crushing, grinding, screening, and beneficiating techniques which are necessary for the upgrading of the iron ore.
