Feb 14, 2020 The crushed ore is put into ball mill and water is added for wet grinding to make it into slurry. The ratio of ore to water in this slurry is 13.5, and the ore with particle size less than 50um should accounts for more than 90. Similarly, the ore with larger particle size needs to be returned to the ball mill after separation by the classifier.
Gold Leaching carbon in leach process is widely used in the newly built gold leaching plants in recent years, and a lot of plants are changing into CIL as well.Gold Leaching CIL process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with high-grade silver.
Generally ball mills are utilized after an initial material crushing or grinding has occurred. Thus, a disadvantage of the ball mill is that the feed size must already be small. Table 2 outlines some typical ball diameters found in ball mills dependent on the staging or purpose of the mill. Table 1 - Ball mill feed and product sizes Callow ...
Jun 05, 2020 Gold vat leaching process is currently widely used in small-scale gold mines, because of a series of advantages including high recovery rate, strong adaptability to ore, low cost and simple process. The basic principle is first to leach the gold from the ore with cyanide solution containing oxygen, and then to extract the gold from the leaching solution with zinc powder or zinc wire.
When the leaching reagentwas Holy, the operating leaching rate of gold was 84.44, and the relative leachingrate of raw ore was 22.58 when the leaching reagent was sodium cyanide, theoperating leaching rate of gold was 88.89, and the relative leaching rate ofraw ore was 23.77.
