Nowadays,the rise of mineral prices means that it is becoming economically attractive to reprocess tailing from old mines. The trouble is that power costs are increasing and government environmental regulations are getting stricter. This means that there needs to be a more efficient grinding mill to process ore that is gentle to the environment. Hongxing Machine grinding mill is designed with these needs in mind. A fine grinding mill is a machine that grinds mineral ore into standard particle sizes for easier mineral extraction.

Tailings, also called slimes, tails, leach residue, or slickens,are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are distinct from overburden or waste rock, which are the materials overlying an ore or mineral body that are displaced during mining without being processed.

There are many ways to extract minerals from ore. For example, when tiny grains of gold are spread through a gravel deposit the gravel is poured onto a table that is coated with mercury. When the table is vibrated the gold grains work their way to the table surface and combine with the mercury. This method works because gold has a strong tendency to combine with mercury. The gold of course then has to be separated from the mercury.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,sand dryer, mobile jaw crusher Welcome all of you to visit our official website.crushing equipment: http://www.crusher-machine.com/

A different method is used to separate sulphide (sulfide) minerals from others in order to obtain their sulphur. In this case the conglomeration of minerals might be finely ground up and then vigorously mixed in a tank of water through which air is being bubbled.

In this process, which is called flotation, the sulphide minerals cling to the bubbles and are collected from the froth that spills over the top of the tank.

As mineral prices soar due to the boom in economies like China and India, it becomes more and more economically viable to reprocess that tailings from old mines using new technology.
