This method has been implemented in the former Soviet Union plant tests, Kazakhstan for processing ore bismuth-containing refractory sulfide ore concentrate. The basic principle is based on the reaction:
This method consumes many kinds of reagents, in addition to hydrochloric acid and sodium chloride, sodium nitrate still need, coal oil and hydrogen peroxide and other agents. The process flow is shown in Figure 1. Technical and economic indicators (concentrate consumption ∕t): HCl 185kg, NaCl 260kg, NaNO 3 3kg kerosene 3kg, H 2 O 2 6kg.

Metal Body Square Water Cooling Tower
This series of products run stable, low noise, energy-saving, in office buildings, shopping malls, hotels, residential areas and other central air-conditioning supporting the use of better results.
The company's standard cooling tower according to the international design conditions design, can also provide customers with non-standard operating conditions or specific sizes under the special, special design.
The circulating water pump suction port shall be located below the water level of the cooling tower catchment basin, and the cooling tower outlet pipe shall not be allowed to be higher than the maximum water level of the catchment basin.
Pipe mounts should be pipe racks and cooling towers should not be allowed to directly bear the weight of the pipes.
The rehydration pipe of the cooling tower should be provided with a support stand to avoid vibration of the pipe when the float valve is rehydrated.
Rehydration pressure should be below 5m water pressure, national standard
The flannage pressure is 1.0Mpa.
When two or more units are assembled, our company will provide a connecting balance tube to balance the chassis water level. The tower top inlet should be set with a conditioning valve in order to enter each
.The water level of the tower is uniform.
The noise is measured at dm1.13VL-W at the equivalent diameter of the cooling tower (Dm1.13VL*W), 1.5 meters above the ground height, wherein L and W are the shape rulers of the tower
inch long and wide).
The use of cellular continuous blister series of diversion,heat dissipation, water collection three-in-one native filler, the whole suspension, gravity cloth water, low drop of water, with cold effect
High, low energy consumption, less drift water, less noise and so on, floating water rate is less than 0.001%.
When connecting different types of towers, the bottom basin water level height of different types of towers must be taken into account, and the base height must be adjusted to maintain the water level balance of the towers.
