Use tailings to recover useful metals and minerals

The tailings are re-elected to make it a secondary resource, which can reduce the cost of dam construction and maintenance of tailings dams, save grinding and transportation, and save more investment in equipment and new process development. Gain more and more attention has been Tailings tail mineral iron ore in a number of metal ore, copper ore, lead zinc ore, tin ore, tungsten ore, molybdenum ore, gold ore, niobium, tantalum, uranium ore, ore etc. Some progress and benefits have been made in mine re-election. Although its scale and quantity are limited, the economic, environmental and resource protection benefits obtained are obvious and the prospects are good.
The challenge of tailings re-election is the recovery of weakly magnetic iron minerals and common, associated metal minerals and non-metallic minerals. However, the weak magnetic iron minerals, the recovery of associated metal minerals, except for a few available re-election methods, rely on a combination of strong magnetic, flotation and heavy magnetic flotation. The key issues to be solved are effective equipment and pharmaceuticals. . The magnetic-floating combined process is used to recover weak magnetic iron minerals. The purpose of magnetic separation is to pre-enrich the useful minerals to increase the selected grade, reduce the amount of floating ore and remove the fine slime. In order to reduce infrastructure and production costs, magnetic separation equipment is required to have a large processing capacity and low cost. The flotation method is used to recover the common and associated metal minerals, because the target mineral content is low; in order to obtain qualified concentrates and reduce the consumption of chemicals, in addition to the pre-enrichment operation, the medicament itself has a strong collection capacity and a high Selective. Therefore, in the future, while researching new high-efficiency collectors , some research work can be carried out on the combined use of existing fatty acid and sulfonic acid agents, so as to complement each other and take into account the concentrate grade and recovery rate. For the recovery of non-metallic minerals in tailings, the combined process of re-floating or heavy-magnetic floating is used. Therefore, it is more important to study the beneficiation process, equipment and medicaments with low cost, large processing capacity and adaptability.

Mini Desktop Cnc Router


The main feature of the Desktop Cnc Router is the small and simple structure under the special spindle design. Various materials can be applied by the machine, such as PVC, Acrylic, wood, PCB, even some soft metal like aluminum and copper. Besides, all the machines are equipped with Mach3 controller. In addition, the machine can achieve the performance of good resolution and less noise with ball screw.

Product Description:


1. Milling and engraving CNC machines allow to realize any of your ideas. All you need is to prepare a model / vector in the program and submit the job to the machine , the rest themselves .
2. UTECH 3040 3axis 800W - is a professional mini- size machine with working area 300 x 400 mm (30 x 40 cm). Has the most powerful ruler in the spindle: XYZ. The spindle has a water cooling - it provides reliability and long service life.
3. Difficult to think of the problem, which cannot handle this car. The only limitation to the possibilities in front of large and heavy brethren: Stage size and speed of processing, and in the aggregate: functionality, compactness and price - out of competition.

4. The machine can easily be placed in a small workshop or home. Will apply for relief 3d- treatment (three-dimensional objects , reliefs, souvenirs, cliche) , engraving (personalization items , creating labels , jewelry , engraving PCBs ) , all types of cutting (letters and labels , signs , models ) , drilling.
