introduction of Gold Ore Crushing

So far, in the world had discovered that 98 kinds of gold ores and carry gold mineral, but common have 47 kinds, and industrial direct use mineral only 10 many kinds.

China has nearly 38 kinds of carry gold mineral substances, the gold ore content are quite generally few, the gravity separation and floatation process are in the gold ore the commonly used preparation method, at present our country big department gold ore uses the above method extraction gold certainly, enrichment plant had very big improvement in the dressing technology and on.

The gold is extremely low in ore content, to withdraw the gold, needs and degrades in size the ore reduction and uses the preparation method to concentrate in advance or causes the gold to separate from the ore.

What in the gold dressing uses are many are the gravity separation and floatation process, the gravity separation law, in the placer gold produces occupies very important status, the mineral separation process is the crag gold mine widely utilization preparation method, at present our country about 80% crag gold mines used this law to choose the gold, the dressing technology and target had the big progress.

In the world has more than 80 national production gold. South Africa occupies the world verifies the gold amount of resources and reserves foundation 50%, accounts for the world reserves 38%; The US occupies the world verifies the amount of resources 12%, occupies the world reserves foundation 8%, world reserves 12%. Besides South Africa and US, the main gold resources country is Russia, Uzbekistan, Australia, Canada, Brazil and other countries. In world more than 80 gold producer countries, Americas' output accounts for world 33% (Latin American 12%, Canada 7%, US 14%); Africa accounts for 28% (South Africa 22%); Asian-Pacific area 29% (Australia accounts for 13%, China accounts for 7%). Yearly produces over 100 tons the country, as mentioned earlier 5 countries besides, Indonesia and Russia. Yearly produces 50 tons - 100 tons countries have Peru, Uzbekistan, Ghana, Brazil and Papua New Guinea. In addition Mexican, Philippine, Zimbabwe, Mali and Kirghiz Tanzania, South Korea, Argentina, Bolivia, Guyana, Guinea and Kazakhstan are also the important gold producer countries.

Gold Ore Mining Process (including crushing process)

First, Crushing process and Grinding process

This process is the main part of crushing and breaking the big gold ores into small bits with gold ore crushing plant. According to the investigation, most of Gold mines choose to buy Jaw Crusher to carry on the coarse crushing, and buy Cone Crusher to complete the secondory breaking or medium crushing , crushing the medium rock into bits.
Then it's time for short head cone crusher machine or vertical shaft impact crusher to crush the bits of gold ore into smaller ones.
Then quarry miners can choose ball mill or raymond mill to complete the grinding process. After that, most of gold ores are ready for next gold production procedure.

The main principle of gold ore crushing processing and grinding process is more crushing while less grinding later.

Second , Recycling Gold Ores

In order to increase the gold mining production rate , gold ore miners can choose ball mill, raymond mill or similar grinding milling machine to recycle gold in gold ore slags .

Third, Floatation process

Before this processing , gold miner should use sand washing machine with belt conveyor , vibrating feeder, vibrating screen to make gold ore bits clean and well-screened.

Gold Ore Crushing Plant

As I mentioned above, in the gold crushing processing , jaw crusher , impact crusher are usually the best choice as primary crushing plant. And Impact Crusher , Cone Crusher , Vetical shaft Impact Crusher can be used in secondory crushing process.

Ball Mill, Raymond mill, MTM Grinding Mill are often used in the grinding process.
At last , in the whole gold mining process , belt conveyor , vibrating feeder, vibrating screen, sand washer are also necessary .
