The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
Platinum platinum mining and extraction methods The mining of platinum ores is similar to gold mining inasmuch as the orebody is a thin, tabular reef covering an extensive area.
Historically, copper bearing ores contain only about % copper, the remainder being gangues or unwanted minerals. Chalcopyrite ore is in this range and can be mined by underground or surface methods.
Mining and Processing Methods. Ores that contain copper in the are typically mined in large, openpits. Copper processing facilities are usually located near mining or extraction sites.

This is either sold for industrial use or used to extract oxide ores of copper by leaching. Stage 4: Smelting with fluxes The calcine is heated to over 1200 °C with fluxes such as silica and limestone.
Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.

On the basis of mining methods used the market can be into categorized as underground mining and, open pit mining. Open pit copper mining is the predominant method used for extraction due to flexible operation techniques, optimized production levels, and relatively low investment costs.
There are two basic types of extraction: surface and subsurface (deep), each relying on a variety of techniques. Regardless of process, legislation requires operators to submit a plan for restoring the land and mitigating acid mine drainage before a permit is granted for mining operations.
This method is also used to mine metallic minerals like gold and copper. The two main types of underground mining in NSW are bordandpillar and longwall mining. Bordandpillar: Bordandpillar, or roomandpillar, is the oldest underground mining technique and was common in NSW before longwall mining began in the 1960s.
