Overview of tungsten tailings re-election

November 28, 2019

Tungsten is often associated with many metals and non-metallic mineral ore symbiotic, so Tailings selected from tungsten, certain metals can be recovered non-metallic minerals or ore. As the main tungsten-producing country in China, eight tungsten-selecting plants have recovered molybdenum from tungsten tailings. For example, the bleaching tailings of the Wutang Tungsten Mine contain 0.0992% MoO 3 , and after flotation, the molybdenum concentrate containing 47.83% MoO 3 is obtained, the recovery rate is 83%, and the output value of the recovered molybdenum accounts for 18% of the total output value of the plant; election bismuth recovery rate of 34.46%. The tungsten tailings from Xiangdong Tungsten Mine contain 0.18% Cu. After grinding, the copper is obtained by flotation of copper to obtain concentrates containing 14% to 15% of Cu. The tungsten ore stellite ore dressing tailings contain 17.5% fluorite , which is produced by flotation. A fluorite concentrate containing 95.67% of CaF 2 and a recovery rate of 64.93%. Brain wolframite Kowloon tailings re-election with BeO0.05%, accounting for 92.96% of beryllium ore containing amount, using alkaline roughing, selection acid method, flotation output with BeO8.23%, the recovery rate of 63.34% Beryl concentrate.
The grade of associated silver in quartz vein black tungsten ore in China is very low, generally 1~2g/t, and the high one is only 10g/t. Although the grade is very low, most of the silver enters the mixed sulfide mineral concentrate with sulfide minerals. Nearly 50% of the silver is lost in the sulfide ore flotation silver mine during separation. Tungsten Iron Mountain ridge this part Sulfide Ore Flotation test recovery of silver, silver-containing grade obtained 808g / t, the recovery rate of 76.05% of the bismuth-containing silver concentrate, leaching using ferric hydrochloric acid solution, and finally A sponge crucible and a silver-rich slag are obtained.

Fan Coil  

Fan coil unit as terminals of Central Air Conditioner. Equipped with main air cooled chiller or Water Cooled Chiller to cool or heat the target place.

Characteristics:

1.Durable construction. Casing of Lark fan coil units shall be galvanized steel panel. And the condensate pan is treated by extruded seamless technology to prevent the leakage. Fire rated thermal insulation is attached to the condensate pan
integrally. Construction of the units is sturdy and permanent.

2.High efficiency. Coils shall be fabricated by Φ9.25mm cooper tubes and hydrophilic aluminum fins. Tubes are expanded
into the fins accurately to confirm the heat transfer efficiency. Fans shall be high airflow rate and low noise
design. And brass headers of copper tubes well distribute water flow configuration to assure optimum heat
transfer efficiency.

3.Low noise and operating cost. Fans shall be specially designed with over-sized galvanized multi-blade centrifugal wheel, operating with low noise, high static pressure and airflow rate. And hi-static, permanent split capacitor motors shall be factory
balance tested for proof the high efficiency and quite operation.
4.Easy maintenance. Motors shall be fabricated with rolling bearing and quenched and tempered steel shaft with antirust treated. Three-speed or LCD thermostat is convenient to control the airflow and room temperature.
5. Low installation cost. Units shall be low-weight design. Drain pipes and wires are easy for connection. The water connection direction and air return are changeable according to the site requirements.
