Innovations: Introduction to Copper: Mining Extraction

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores.

COPPER Copper production - Repository

Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate (Optional partial roasting to obtain oxidized material or calcines) 2. Two-stage pyrometallurgical extraction 1. smelting concentrates to matte 2. converting matte by oxidation to crude (converter or blister) copper 3.

The grade control process is described below: DRILLING: Drill burden and spacing are based on the rock types present at Skorpion , e.g. 4 m x 4 m in ore and 6 m x 6 m in waste material (Figure 2). SAMPLING: Samples and drill chips are collected over intervals of 2.5m, 5m or 10m.

Copper Smelting - an overview ScienceDirect Topics

Copper smeltingplants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several Pierce-Smith converters operated in batches. Automating scheduling provides advisory information to operators.

Impacts of copper mining on people and nature

The mining industry uses sulphuric acid in the extraction and treatment of copper. The extraction processes are called heap and situ leaching; during these processes, particles react with each other to create acidic mists that not only harm people’s skin, eyes and

From Ore to Finished Product - Copper

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Impacts of copper mining on people and nature

The mining industry uses sulphuric acid in the extraction and treatment of copper. The extraction processes are called heap and situ leaching; during these processes, particles react with each other to create acidic mists that not only harm people’s skin, eyes and lungs, but also destroy crops, deteriorate the quality of the land, and damage nearby buildings.
