What does a concentrator do in mining?

A Knelson concentrator is a type of gravity concentration apparatus, predominantly used in the gold mining industry. It is used for the recovery of fine particles of free gold, meaning gold that does not require gold cyanidation for recovery.

What is ore blending?

Ore blending generally refers to the blending of existing ore according to the production index before ore dressing. The purpose is to make the mixed ore properties more convenient for production, thus improving production efficiency and reducing production cost [1].

How do you separate rocks from ore?

How do you concentrate copper ore?

Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.

How do you clean raw copper ore?

Soak in muriatic acid (hydrochloric) approximately 1 hour. Sometimes toilet bowl cleaners contain this acid. This soaking removes all the green/brown oxidation from copper, plus any calcite is dissolved. Rinse well and brush the copper and rock again to remove any further loose rock.

How do you extract ores?

What is copper concentrator?
