Over the years the output of grade copper decreased with increasing depth of the mine. This was proposed to be compensated by manufacturing copper cathode which was priced higher. The estimated ore reserve was 1.54 billion tons. The copper concentrate production rate of 130,000 tons was envisaged by Erdent. [3]

Today there are about 25 abandon sulphide mines around the Troodos Mountain. Some of the mines are partly restored for purposes of access, prevention of the acidic drainages and reduction of the visual disturbance. A couple of copper mines have been restored or are under restoration by the land owners, in order to reuse their land.

26/06/2020Copper can be mined using either surface mining methods or underground mining method depending on the existence of the ore body. The ore is then pulverised to improve the homogeneity in the mined ore when being sampled as copper concentration varies considerably in the ore. The pulverised ore can be sold as it is.

The Basics of Copper Mining and Processing Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu2 S+O2 → 2Cu+SO2 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 Copper; 98 – 99.5 % pure.
