flotation of copper ore

Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence , Increase its market value. Common production lines are: stone production line and sand production line.

Stone production line

On the basis of the stone production line, sand making machine equipment for fine crushing and shaping is added, which can realize the simultaneous production of machine-made sand and crushed stone. The entire production line is flexible in construction and diverse in output, which can meet the various processing requirements of customers. , To achieve the purpose of "one line with multiple uses", it is an ideal production line choice for producing highway surface materials, high-speed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

13/04/2016  Copper Ore Grinding. Porphyry copper ores usually are medium to medium hard and require grinding to about 65 mesh to economically liberate the copper minerals from the siliceous gangue. Sometimes a regrinding circuit is advantageous on the rougher concentrate and on the scavenger concentrate. This will liberate the mineral from the middling products and increase the recovery by putting those mineral particles into the concentrate. Rougher flotation
