Gold Ore Processing Plant

Gold Ore Processing

At the Processing Plant, gold and silver are extracted from the ore. The gold processing plant alternates between treating ore from the Martha Mine open pit and from the Favona underground mine.

Ore processing consists of the following stages:

  1. Addition of process water to form a slurry
  2. Addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution
  3. Addition of carbon to adsorb dissolved metals and remove them from the slurry
  4. Stripping the metals from the carbon by acid washing and circulation of a caustic cyanide solution
  5. Pumping of the barren slurry (tailings) to the tailings storage facility.
  6. Zenith Processing Plant has the capacity to treat up to 1.25 million tonnes per annum of ore.

Gold Ore Crushing Plant

gold ore plantGold ore is crushed because the leaching process recovers mostly surface gold and crushing maximizes the surface area of the ore for greater gold recovery. The crushing circuit is designed to process almost 3,000 tons of ore per hour, approximately 50 tons per minute.

Gold ore is loaded into the primary crusher for initial sizing. This gyratory gold ore crusher breaks the rock into 6-inch diameter pieces. Conveyor belts take the broken ore to the screening plant, which runs the ore through vibrating screens to size the material.

The optimum size is 0.75 inch diameter pieces. Oversized rock is sent via conveyor to the secondary gold ore crushing plant. When crushed to 0.75 inch diameter or smaller, lime is added to the ore to increase the effectiveness of the process solution. The ore is then conveyed to the load out bin.

Gold Ore Grinding Mills

Gold is often found associated with the mineral ore. It is sometimes associated with other minerals as well, including iron and manganese oxides, calcite, pyrite and other sulfides as well. Often, when you finish the gold ore crush, you need grind it with gold ore grinding mills.

Gold ore grinding process plays an important role in gold ore mining. The gold ore grinding mill grind the crushed ore minerals into fine even ultrafine powder so that the leaching and smelting process can go smoothly.

Ore grinding mills can be divided into wet grinding and dry grinding. According to the different application, there will be open-circuit grinding and closed-circuit grinding process. Our engineer will design different grinding lines for your gold ore grinding requirements. The most popular ore milling machine are ball mill, raymond mill, trapezium mill.

Gold Ore Crusher >>

Gold ore crusher also named gold crusher is a widely used stone crusher in ore mining industry for crushing. According to the gold ore crushing process, Zenith can supply you all kinds of equipments such as primary gold ore crusher, secondary crusher and final ore crusher etc.

Zenith jaw crusher is the most widely used gold ore crusher in primary processing such as Zenith PE jaw crusher and PEW series jaw crusher etc. Different gold ore crusher should be selected according to the crushing ratios and final products size.

Zenith impact crusher is applied in gold ore mining named gold impact crusher or gold impactor. Hydraulic impact crusher is usually used as secondary gold ore crusher in the crushing plants and gold ore grinding plants.
