These deposits are mined, crushed and ground, and then concentrated first by gravity separation to recover coarse particles of native gold before being subjected to froth flotation to concentrate the sulfide mineral fraction that Gold ore production process includes crushing, grinding, beneficiation three processes. Currently,the gold ore processing methods are as follows: First of all, Gold Ore Crushing Process and Gold Crusher sbmchina

(Richiewiki, 2010). The gold ores are usually big and. have to be crushed to reduce them to a size of about 12mm diameter before pure gold can be extracted from As crushing only does not generally liberate a mineral, further size reduction is usually required. This is achieved by grinding the crushed ore in tubular mills or Tubular Ball Mills ScienceDirect

Richards gives the average amount of water used in 21 mills as 2.77 gallons per stamp per minute, or 6.68 tons of water per ton of ore crushed. The average duty of a miner’s inch in a gold stamp-mill is given by P. M. Randall as 12 tons of quartz if the head under which the water is supplied is 4 inches, and 15.88 tons if the head is 7 inches.The crushed ore then enters a grinding circuit consisting of six grinding mill lines. Each line consists of a 12.2 m (40 ft) diameter × 11 m (36 ft) long AG mill with a 28 MW gearless motor in closed circuit with a pebble crusher and primary classifying cyclones.

After ore is mined, it first needs to be crushed and ground to suitable particle size. Semi-autogenous grinding (SAG) mills are widely used, large-scale grinding machines that generate a grinding effect through the impact and abrasion of a small amount of grinding medium and ore clasts of different sizes [].This process can complete the The purpose of a gold mill, at least a simple one, is to crush and grind rock fine enough to release small particles of gold. After liberating the gold from the rock or gangue, it is then run through a gravity separation step, which will concentrate most of the gold and wash off the lighter waste rock.

The crushed ore is transferred to a semiautogenous (SAG) mill or ball mill where the ore is further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; The results show that grinding time is a significant factor affecting the particle size composition. The suitable grinding concentration of Tongkeng ore and Gaofeng ore is 70% and 75%, respectively. The effect of mill filling ratio on Gaofeng ore is not obvious. The rotational rate has little effect on the grinding technical efficiency.Special Issue "Grinding Modeling and Energy Efficiency in Ore

A gold mill can be divided into 4 major areas: ore mining and size reduction, leaching, gold recovery, and tailings disposal. Once the ore is removed from the ground it is crushed in 1 to 3 stages to prepare the ore for grinding.
