Traditional Surface Mining Methods EXCELLENCE IN MINING

Jul 23, 2016 Traditional surface mining can be classified into two groups on the basis of the method of extraction: Mechanical extraction or aqueous extraction. The primary differences between these mining methods are the location of the ore body and the mode of mechanical extraction.

Traditional mining Wikipedia

Traditional mining, also known as mining, is a mining method involving the use of simple mining tools, such as shovels, miners, hammers, chisels and pans.

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 (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as get price

2. Mining Methods Copper

In each of these mining methods, various earth-moving equipment including shovels, dozers, hauling trucks, and loaders are used to remove and transport the ore. However, the first step is to loosen the rock in the ore body so that it can be moved and processed. Blasting and grinding equipment are used to accomplish this task.get price
