Under normal circumstances for roughing, cleaning, sweeping election for flotation (mining flotation), magnetic separator (dry-type magnetic separator, wet magnetic separator, magnetite mineral processing equipment) and other mineral processing equipment .
After the initial sorting ore, such as flotation, gravity separation or magnetic separation, to which some of the water content of gangue or rock elected, but was higher than the ore grade of the product, known as crude concentrates, as a general not meet the quality requirements of concentrate, the process known as roughing services. The crude concentrate to be eligible for re-election of concentrate, which called the selection process work. Sometimes the need to concentrate through the rough times to get qualified selection of concentrates, followed by its operation as a selection, second selection and third selection ... ....
Tailings can not generally rough as the final tailings, processing operations are often needed to enter the next step, this operation is called scavenging. In order to improve metal recovery, sometimes after several elections in order to obtain final debris sweep.
Ore processed through the sorting operation to remove most of the gangue and impurities, so that useful minerals were enriched product called concentrate. Concentrator Concentrate is the final product, sometimes called the final concentrate, generally as a raw material for smelting. Concentrate to the final major components and impurities it has reached the national standard, can be called qualified concentrate.
For concentrates, the ore, tailings, after each flotation concentrate and tailings in the mine is called outside.
An ore processing through the sorting operation, its main components have been enriched in the concentrate, and some through an integrated approach, the ore or other minor elements associated metals are also recovered. So, while the remaining part of the product with ingredients containing low, this part of the product known as tailings, or call the final tailings. It should be noted that in the tailings still contain technical level by the current limit and is difficult to extract useful components, but in the future may become re-use of materials. Therefore, the tailings pile will generally stored in the tailings.
In the sorting process are known as intermediates in the mine. Useful ingredients in the ore generally ranged between concentrate and tailings. In the sorting process, in general need to return to proper operation of the mine site, or they were treated separately.
