Raw ore, concentrate, tailings|  unknown ore testing and identification


The ore just extracted from the mine is the raw ore, which is crushed and then goes into the first flotation process, i.e. rougher separation, resulting in rougher concentrate and rougher tailings.


The coarse tailing is then flotation, i.e., sweeping, which produces sweeping concentrate and sweeping tailing.


The coarse concentrate is then flotation, i.e. selected, to produce a concentrate and a concentrate tailing.


After the initial separation of the ore, such as flotation, re-election or magnetic separation, the water content of some of the veins or peridotite selected, and the product higher than the original grade, called coarse concentrate, generally not up to the requirements of the quality of the concentrate, this process is called coarse separation services. The coarse concentrate will be re-elected to get qualified concentrate, this process is called selection operation. Sometimes it is necessary to select the coarse concentrate several times to get qualified concentrate, and the operation is called primary selection, secondary selection and tertiary selection in order ....... 



Generally, the rougher tailings cannot be discarded as the final tailings, and often need to enter the next step of the operation, which is called sweeping. In order to improve the metal recovery, it is sometimes necessary to go through several sweeping operations to arrive at the final tailings.


After the ore has been processed by the separation operation, most of the veins and impurities are removed, so that the useful minerals are enriched product is called concentrate. The concentrate is the final product of the beneficiation plant, sometimes called the final concentrate, and is generally used as the raw material for smelting. The final concentrate has to make its main components and impurity content meet the national standards in order to be called qualified concentrate.


For concentrate, medium ore and tailings, what is outside the concentrate and tailings after each flotation is called medium ore. 


After a raw ore is treated by the separation operation, its main components have been enriched in the concentrate, and in some cases, after comprehensive treatment, the minor components of the ore or other associated metals are also recovered. So the remaining part of the product contains very low components, and this part of the product is called tailings, or final tailings. It should be noted that the tailings still contain useful components that are difficult to extract due to the current level of technology, but have the potential to be reused as raw materials in the future. Therefore, the tailings are generally stockpiled and preserved in tailings storage. 


Analysis of unknown ore minerals

Ore testing types 1, geological and chemical exploration: census samples, slot (pit) samples, drill samples, dispersion flow samples, secondary halo samples, primary halo samples, etc.

2、Ore minerals: copper, lead and zinc ore, gold ore, molybdenum ore, tungsten ore, titanium ore, tin ore, antimony ore, bismuth ore, mercury ore, cobalt ore, nickel ore, chromium ore, iron ore, manganese ore, phosphate ore, fluorite, bauxite, sulphide iron ore and rock analysis, etc.

3, concentrate products: copper concentrate, lead concentrate, zinc concentrate, gold concentrate, tin concentrate, antimony concentrate, tungsten concentrate, molybdenum concentrate, etc.

4、Mineral products: various concentrates (beneficial and harmful impurity components), imported raw materials and smelting slag materials, etc. ‍

Ore is rich, various metal types and content varies, fine detection technology reference national ore detection standards, to provide you with all kinds of ores, copper, lead, zinc, nickel, tin, cobalt, aluminum and other non-ferrous metal content analysis, detection, identification services, as well as gold, silver, palladium, platinum and other precious metal content of the assay analysis services, each element detection methods are in strict accordance with the relevant national testing standards, and can do accurate and fast.
