Gold ore beneficiation plant

According to the structure of state and gold content of gold, gold ore can be divided into the gold mineral gold deposits, gold-bearing ore and ore containing gold three categories. The so-called gold mineral gold deposits is the main target of industrial development and utilization.Gold ore beneficiation process is generally divided into several stages, crushing, grinding, classification and separating. The current gold ore beneficiation process, generally through the crusher crushed the raw ore, and then into the Ball Mill smashed through the gravity separation, flotation, extracted from the concentrate and tailings, and through chemical methods, and finally through the smelting of gold and its products eventually become finished products.

Gold beneficiation equipment is mainly consisted of Vibrating Feeder, Jaw Crusher, Ball Mill, Classifier, Magnetic Separator, Flotation Machine, Condensing Machine, Spiral Separator and Drying Machine. With the equipment Feeder, Hoister and Conveyor, a full set of Beneficiation Equipment Production Line can be made. It features as High efficiency, Low Consumption, High Output and economical and reasonable, etc.

The general beneficiation process of gold ore is below: Primary Crushing—-Secondary Crushing—-Sieving—-Third Crushing—–Grinding— Classifying—–Lower Magnetic Separation—-Strong Magnetic Separation—-Filtering—- Concentrated ore.

In the gold ore processing plant, the gold ore should be crushed by jaw crusher initially. When it gets the reasonable fineness, gold ore particle is transported into ball mill by elevating conveyer and feeder, and is milled by ball mill. The subtle milled gold ore gets the next procedure: classification, and the mixed gold ore can be classified by screw classifier. The classified gold ore gets into magnetic separator. Since the specific magnetization coefficients of ores are different, the magnetic substance of mixed gold ore is separated from others with magnetic and mechanical force. The mineral matter, which has been separated by magnetic separator initially, is transported into flotation machine by conveyer, and different medicines are added according to different characteristics of gold ore, so that the needed gold ore is separated from others. Since the separated ore are wet, they should be dewatered by thickner initially, and dried by dryer.

A gold beneficiation process, the process uses two and a half of a closed-circuit crushing, two stage two closed-circuit grinding and flotation and then by selection, selection of its tailings swept away by a rough sorting operations, will be selected tailings and sweep the election together combined ore concentrate regrinding, the high efficiency of this process broken, broken fine-level content and the final product was 81.55%, high crushing capacity, processing capacity per hour is 53. 84 tons, working time is short, and the sorting effect, high-technology index, and the concentrate grade and recovery rates can improve synchronization, high recovery rate targets, increased 3.03%, concentrate grade increased 16.57g/t.
