Sep 14, 2013· Copper sulfide ores are first treated by a process called flotation. In this process, bubbles are produced in a mixture of ground copper ore, water, and chemical reagents. The particles of copper bearing minerals in the ore stick to the bubbles and

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 S+O 2 2Cu+SO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final product to have a very blistery appearance and hence it is called Blister CopperEstimated Reading Time: 2 mins
The flotation of a natural porphyry copper ore with bornite and malachite was investigated via fundamental work with pure minerals and a bench scale testing regime. The processing of the test ore was problematic due to a mineral assemblage that caused prevalent slime generation.
The Flotation Process. Until quite recently copper ore had to be hand picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper.
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals, the ore
After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: Ratio of concentration % Metal Recovery % Metal Loss % Weight Recovery, or % Yield Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotationFile Size: 659KB

This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using. Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of ...
