The technical operating conditions for granulation heap leaching are controlled as follows: 1. Number of binders   As a material for the binder, cement and lime are currently used, and the former is good, and the dosage is about 5 kg / ton. The binder should be added to the relatively dry ore, mixed with the ore and then wetted. When the raw material to be piled is tailings, the binder is preferably half of cement and lime. 2. The amount of water added to the mixture of raw materials and binder   In general, the wet material after granulation is preferably formed into a block when pressed in the hand. And the particle size depends on how much clay content ore moisture, when raw ores, the moisture content is 8 to 16% of the raw material, when the material is tailings, water content is 18 to 22% of the starting material. 3. Curing time   The curing time required for the ore to form a silicate bond is an important factor in determining the strength of the agglomerate. The curing time of the raw ore raw material is 8 hours, and the curing time of the tailings raw material is 24 hours. 50 Television,50 Inch Hd Television,Television Digital,50 Inch Smart Television Jiangsu Hengye Precision Technology Co.,Ltd , https://www.hengyejmtv.com
