With the continuous copper ore mining, there is fewer and fewer high-grade copper ore, and copper ore block size is getting smaller and more complex. Ordinary flotation process seems not available for those ore. At this time, "poor, fine, miscellaneous" copper ore dressing process - the biological leaching process was born. The following is a brief introduction of biological leaching of copper production line. Common microbe mineral processing technology are heap leaching and leaching. Heap leaching means to heap mined ore, and then use microbe leaching solution. Due to its production cost is low and less pollution, it has been widely used. Situ leaching is to use a chemical solvent or microbial leaching solution to inject underground mines copper and dissolve copper and other valuable metals, then collect the dissolved rich liquid. This kind of processing method is the combination of mining and mineral processing, and there is no need to ship the ore out the ground whic...

Mineral, as an essential part, is widely used in our daily life. Metalware, buildings, even food and medicine, are all consisted of mineral. Mineral through the complex process, transforms magically from huge stones to the raw material of our daily life production. Most minerals are buried under the ground, as the compound state. There are many impurities in them, which cannot be used directly. So mineral processing is an important part. Although the input of processing could just be 20%-30% of the total input, the output of it could be 90% of the total. So that the design and construction of processing plant is quiet necessary of all. Xinhai, holding the idea ‘what you need is what we can do’, has accomplished over 500 mineral processing EPC project from over 90 countries, with 88 patents.

As the increasing exploration of global mineral resources, the concept of “useless tailings” has completely eliminated by the mineral processing industry. Instead of this, the tailings is recognized as the potential resources with the highest secondary utilization rate. Taking China as an example, the total tailings volume has accumulated for 60 billion tons and the annual emissions are up to 1.6 billion tons, but the comprehensive utilization rate of tailings is only 18.9%. So, most of them have not been comprehensively developed and utilized. In addition, since the propose of “green mining” in 2008, China has successively published a series of policies and regulations to advocate “green mine” construction, and listed the tailing discharging in the latest Environmental Protection Laws of PRC, which explicitly stated that 15 yuan taxes should be paid for every ton of tailings. All in all, the increasing tailings emissions, the resulting environmental pollution and safety problem, as...
