The most common separation method for placer gold is gravity separation. However, placer gold flotation mining equipment or gold recovery equipment is needed for gold ore with very fine particle size and wide range of dissemination size.Xinhai has provided placer gold mining equipment and gold recovery equipment for many years, gold mining equipment and gold recovery equipment of Xinhai has high quality and reasonable price.
among the placer gold mining equipment or gold recovery equipment, leaching agitation tank and scrubbing thicker are frequently used. Thereto, leaching agitation tank of gold mining equipment is represented by single impeller agitation tank and double-impeller agitation tank. The mining flotation equipment or recovery equipment of gold ore with single impeller, also called axial flow leaching agitation tank, is designed and manufactured by China Central Engineering Institute for Non-ferrous Metallurgical Industries. It works well under the following conditions, relatively bigger density, higher viscosity, fast settling velocity, more than 85% of -200 mess particles and gold leaching and absorption with less than 45% of slurry concentration. When the impeller rotates clockwise, the blade immersing in the slurry will produce thrust, driving the slurry to flow into the blade along the top of circulating cylinder and then flow downward along the cylinder via the guide blade. When slurry flows through the circulating shell, it transverse flows and then flows upward along the circulating cylinder wall, forming a closed cycle. Such kind of gold ore mining equipment or gold recovery equipment with single impeller leaching has the following advantages. First, it has good mixing performance with small energy consumption, big axial velocity, small radial velocity and intense drop plate strength. Second, located above the slurry sedimentation area, the impeller is easy to launch with small power. Third, with simple structure of inflation device, it can inflate uniformly and achieve the full mixture of air and slurry. Meanwhile, the gold ore mining equipment or gold recovery equipment with double impellers is usually used for the separating operation of slurry with more than 90% fineness and less than 45% concentration.
Mainly engaged in gold ore separation, Shandong Xinhai Mining Technology & Equipment Inc is a big company with placer gold mining equipment or gold recovery equipment manufacture combined with technical guidance. In research of gold ore, Xinhai has very mature technology with nearly 30-year experience; when talking to providing gold mining equipment or gold recovery equipment service, Xinhai can supplies the excellent service and advanced technology that cannot be substituted by other manufacturers.
