Introduction to Gold Mining

1.Rock is removed from the mine.Rock containing gold, is hauled to the Crushing Facility. Rock
without gold is taken to the overburden storage areas.
2.Large haul trucks are used to move the rock from the Mine to the crushing Facility, or to the
overburden storage areas.
3.Ore is processed at the two stage Crushing and Screening Facility,and hauled to the Valley Leach
4.The Valley Leath Facility is a lined, zero discharge area where dilute sodium cyanide process
solution dissolves the gold, and is captured in the bottom of the lined area.
5.The gold is recovered from the process solution with a carbon adsorption process. The final product
is a gold and silver button called Dore.
To separate the gold from the ore collected by the diggers in the mine tunnel, the ore was first crushed by a series of hammers in the stamper head.

The crushed ore was then run over copper plates that had been treated with cyanide and then tinned with “quick-silver” (mercury). Mercury has a chemical affinity to gold and hence catches it. The resulting mixture was then heated to evaporate the mercury until only the gold remained.

This method of extraction was used for many years although it was generally accepted that it was only 60% effective.

Gold Mining Applications

Gold is a precious metal mined to create practical and ornamental pieces of work. Refined gold ore can be melted, poured and cast into almost any shape to make jewelry. There are numerous industrial applications for gold, as well. Many electronics and medical devices rely on gold’s ability to conduct electricity and resist corrosion. Here’s how to identify gold ore.

Gold-Ore is an international mining and exploration company with one operating gold mine and several gold and base metal exploration properties at various stages of development. The Bjorkdal Gold Mine and the company’s exploration properties are all located in the safe, highly developed and mining friendly jurisdiction of Sweden. Bjorkdal, is currently producing gold from both underground and open-pit operations at an annualized rate approaching 40,000 oz/year. The company is currently focused on expanding the resource base at the mine through development drilling, while also searching for new deposits on highly prospective ground surrounding the minesite. The physical assets of the company are complemented by an experienced operations team at the Bjorkdal Mine and an experienced management team, located in Vancouver, Canada.

Gold mining machine

Gold mining machine has an important role in gold mining industry. NFLG is a professional gold mining machine manufacturer of gold ore cursher ore gold mining crusher and gold mill machines. In gold mining, high technology gold mining equipment, such as gold detectors, elegant modern dredges, and lightweight sluices will be needed.

Gold crusher is also used as the primary crusher for crushing gold ore in gold ore crushing industry. Jaw crusher is the most used gold mining machine for crushing ore. Jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. So gold jaw curshers are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc.

Gold mobile crusher is the newly type of gold mining machine for gold crushing. Gold ore mobile crusher can eliminate the obstacles of the crushing places and circumstances, and offer the high efficient and low cost project plants for the client. To the client, gold mobile cursher is the best choice as a gold mining machine.
