The mine-to-mill project in the same mine identified further benefit, specifically the marked reduction in SAG feed size and throughput variability [5]. A second but important benefit was the reduced wear in the gyratory crusher, resulting in a significantly longer period between relines. When electronic detonators with very short delay time were applied in the Chuquicamata open pit copper ...

Copper Industrial History of Cumbria

The richest copper mine known at that time was named by the Germans ‘Gottesgab’ – God’s Gift – which became corrupted into Goldscope, the name it is known by today. They started there at Easter 1556, working on a vein up to 9 ft thick. By 1568 the Company of Mines Royal had been formed, and the mines of the Caldbeck Fells received a first mention in their accounts for this year.

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper

Mill liners need to protect the mill shell from damages due to wear and transmit the energy from the rotating mill to the ball charge. The rules that guide the design of a liner depend on the grinding mechanisms required for the specific mill. They can be classified either as impact/cataracting for very coarse to coarse grinding, cascading for coarse to medium grinding or attrition for medium to fine
