Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.

EP0229835B1 Process for the selective separation of a

A process for separation of the mineral components of a copper/molybdenum sulfide ore by flotation including (a) crushing and grinding the ore to liberate the minerals; (b) in a primary flotation circuit, adding a molybdenum collector selected from the group of hydrocarbon oils, and a frother; (c) floating a primary (molybdenum) concentrate in the primary circuit in the absence of a copper

Copper ore processing technology development and research

Since the introduction of hydrometallurgical process for copper in the late 1980s, it has been widely used in China, especially for copper-bearing materials that cannot be effectively recovered by conventional processing methods, such as waste rock from open-pit ore stripping and low-grade copper oxide ore. Hydrometallurgical process is the

the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods of cop-per production have remained unchanged for 65 years.

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

Liquation Wikipedia

Liquation is a metallurgical method for separating metals from an ore or alloy.A mixture of metals is melted together with a third, after which the mixture is separated by liquid extraction.This method was largely used to separate silver from copper using lead, but it can also be used to remove antimony minerals from ore, and refine tin

Copper-molybdenum ore beneficiation,flotation separation

For copper sulfide ore, when it uses xanthate as a collector, it has the best floatability, but usually a lot of inhibitors are needed to suppress it. 2.Copper-molybdenum mixed concentrate separation process . For the flotation separation of copper-molybdenum mixed concentrate, it can usually be divided into 3 steps. ① Pretreatment.

Copper-Lead-Zinc ores Danafloat

Copper-Lead-Zinc ores. The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage. In this case, as a general rule because both copper and lead

Copper ore contains lightly oxidized sulfide ore, and the copper in the ore is mainly in copper sulfide minerals.

Eliminating Copper from Gold Ore

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper
