Breaking material down is a type of unit operation .Mill (grinding) - Wikipedia,Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process. Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material. In tower mills, there is no cascading action as in standard grinding mills. Stirred millsMining - Wikipedia,The water mills were employed in crushing ore, raising ore from shafts, and ventilating galleries by powering giant bellows. Black powder was first used in mining in Selmecbánya, Kingdom of Hungary (now Banská Štiavnica, Slovakia) in 1627.

Mining - Wikipedia

Ore mills generate large amounts of waste, called tailings. For example, 99 tons of waste are generated per ton of copper, with even higher ratios in gold mining – because only 5.3 g of gold is extracted per ton of ore, a ton of gold produces 200,000 tons of tailings. (As time goes on and richer deposits are exhausted – and technology improves to permit – this number is going down to .5,Round Mountain Gold Mine (MRDS #10310392) AU, AG,The Round Mountain Mine was the first major gold mine in North America to be established on the basis of heap leaching as the principal mode of ore processing. Production began in 1977. A deeper disseminated ore zone was subsequently discovered and by 1981 had increased the proven and probable ore reserves to 195 million tons averaging 0.043 opt gold.

The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
