Alluvial gold mines is various in kinds and widely distributed. According to the transport distance, the alluvial gold mines can be divided into residual placer gold, slope placer gold mine, alluvial placer gold mine, riverbed impact placer gold mine, and coastal placer gold mine. Among them, the riverbed impact placer gold mine is common. According to handling force medium, the alluvial gold mine can be divided into aeolian placer gold mine, ice-forming placer gold mine, and aquatic placer gold mine. According to the era of transport, the alluvial gold mine can be divided into deep placer gold deposit, terraced placer gold mine, and river beach placer gold mine. There is very low content gold in the alluvial gold mine. It needs all kinds of gold processing equipment for processing and enrichment. The gravity separation has the characteristic of high-efficiency, energy-saving and environment-friendly. It is the main alluvial gold mining method. Generally, gold and various kinds of associated heavy minerals can be recovered through gravity separation. Then gold and associated heavy sand minerals can be separated through gravity separation, flotation, magnetic separation, and electrostatic beneficiation.
Based on the above problems, the gold tailings disposal methods and comprehensive utilization of gold tailings is extremely urgent. At present, the common gold tailings disposal methods and comprehensive utilization mainly include the following ways: gold tailings reprocessing method, gold tailings dry stacking method, production of building materials, mine filling, reclamation and making field.
At present, the common chrome extraction processes mainly include gravity separation, magnetic separation, electric separation, flotation, gravity-magnetic separation process. Below, let’s take you to learn about each chromite ore processing process.
Hematite is a kind of weak magnetic minerals, it is hard to get hematite concentrate by single magnetic separation process (including roasting magnetic separation and magnetic separation). Therefore, Xinhai often combine magnetic separation process with other hematite ore dressing processes rather than adopting single magnetic separation process
The common limonite beneficiation process of Xinhai mainly includes grinding, gravity separation and reverse flotation process.
Lead and zinc ore dressing technology is different due to the ore type. With the improvement of lead and zinc ore dressing technology, the lead and zinc ore commonly adopts gravity separation – floatation process, magnetic separation – floatation process, gravity separation - magnetic separation - floatation process and so on.
In the past 20 years, Xinhai successfully completed hundreds of mineral processing EPC plants by relying on its accurate technical support and perfect service, and received the consistent praise from customers. The following lead-zinc ore processing plant in Chamdo, Tibet was a successful case of Xinhai mineral processing EPC service.
For decades, the heap leaching process has developed rapidly with the technical progress and innovation, and a lot of experience and knowledge have been accumulated in the design.It has the advantages of small investment, low cost, short construction time and less production, so it has been widely spread in the world.
The working condition of a processing plant is constant and choosing the best processing solutions is related to the ore nature. Taking Jiangxi Dexing copper mineral processing as an example.
Phosphate is a kind of important biological element constituting the cell of animals and plants. South Africa is a big country producing phosphate, there is a rapid growth trend of the demand for phosphate fertilizer in recent years because of the further agricultural development.
1,200t/d gold ore mineral processing plant in Cambodia was completely contracted by Xinhai.
Entrusted by the owner in QInghai, Shandong Xinhai Mining Technology & Equipment Inc. carried out mineral processing test and study on the gold-antimony ore.
More than 10 million of gold tailings were stored in the tailing pond in North Korea. The average gold grade of the tailings was 1g/t, and the recoverable valuable element was gold.
There was a gold mine in Têwo which had been small-scale mined, and processed by stacking and heap leaching for a long term.
700t/d gold ore mineral processing plant in Zimbabwe was contracted by Xinhai. The plant adopted the CIL technological process.
