Crusher for Gold Mining and Processing Line

With gold widely used in industry, gold mining and processing developed quickly. And the need of gold ore crusher increased significant. Here we will introduce two kinds of crusher for gold mining for you.

 Applications of Gold

Gold is one kind of the rarest and most precious metals. It is with the features of soft and corrosionresistant. The color of gold is golden yellow, and with a metallic sheen. Its hardness is about 2 to 3. For physical characteristics, gold is with good ductility, high thermal conductivity and electrical conductivity.
Since gold has excellent stability, good electrical conductivity and thermal conductivity, so the uses of it become wider and wider in the electronics industry. In the chemical industry, gold also has a unique purpose. It can be used as the materials in nuclear chemical plants, man-made fiber factory, and so on.And at the same time, gold is still has some gold consumption in the traditional industries, such as photography, pens, dental, and other industries.

Gold Ore Mining Industry

Because of a wide range of applications, gold ore mining and processing developed greatly in recent years. Since the 21st century, the world's gold production stabilized at an average of 2,600 tons. Gold ore is very unevenly distributed on Earth. Though, there are more than 80 countries produce gold in the world, the gold productions are quite different among these countries. In 2004, the world's top 10 gold production countries are South Africa, USA, Australia, China, Russia, Peru, Canada, and so on. While gold production has increased in some countries, such as Australia, Peru, Indonesia, but gold production in South Africa, the United States and other gold producing countries has declined.

Gold Ore Processing Line

Gold ore beneficiation process includes preparing operations and sorting operations. Prepare job mainly consists of two processes, they are crushing and screening. Crushing process is mainly to crush the large of gold ore into small pieces, and to separate the clay mineral from metal particles. Screening process is mainly to screen the coarse particles which without gold out. Commonly, flat screen and cylindrical sieve are usually used as the gold ore screener. As for gold ore beneficiation, gravity separation method is mainly used. On the one hand, the proportion of placer gold (average 17.50 to 18.0 mm) is bigger than coarse grain (typically 0.074 to 2 mm). On the other hand, gravity separation method is one kind of relatively economical and simple beneficiation method. Jigging machine and shaking table are the commonly used beneficiation equipment of gold ore.

Crusher for Gold Mining

According to the survey, people usually adopt jaw crusher for primary crushing in gold plant. And then, adopt cone crusher and impact crusher for secondary crushing and fine crushing. In order to increase the production capacity, we need to adopt efficient gold production equipment and improve the processing technology.

PEW series jaw crusher is common gold ore primary crushing equipment. It is designed based on the traditional jaw crusher. It is suitable to process all kinds of medium-grained into small pieces. It is often associated with cone crusher, grinding mill and other equipment to form a complete gold ore processing line. Its structure is stable and reliable, so the performance of it is quite outstanding. The crushing chamber of it adopts a "V"-type structure, which effectively increasing the crushing area and improving the crushing rate and yield.

HCS series single cylinder hydraulic cone crusher is a high efficiency gold ore crusher.Compared with similar products, it has great advantages. It can meet the demands of gold ore medium and fine crushing. It is with the features of simple structure, reliable performance, and stable operation. And this cone crusher is equipped with hydraulic adjustment and hydraulic protection device. Soit is easy to clean the chamber. As a result, it can effectively save the downtime.
