Lime-mineralization agent

Lime: Limestone (CaCO3) is calcined and decomposed into quicklime (CaO) and carbon dioxide at a high temperature of 1200 °C. The quicklime is abbreviated as lime, and the quicklime is easily absorbed into slaked lime (Ca(OH)2). The slaked lime is a white powdery substance, which is not easily dissolved in water. It is usually added directly to the ball mill or the agitation tank before flotation in the flotation operation. It can also be adjusted into lime milk with water during stirring, and then added to the flotation machine. Calcium oxide is a strong base, and the calcium hydroxide dissolved in water is completely ionized, making the solution strongly alkaline.
Lime is the cheapest slurry pH adjusting agent, in a multi-metal sulphide deposits, the use of flotation, the pH of the pulp used to improve the lime, so that pyrite is suppressed. Lime is a typical inhibitor of pyrite. Generally, some pyrite can be floated in weakly acidic pulp, and some can also be floated in neutral or alkaline pulp. After the surface of the pyrite is oxidized, it will not float well when the pH is greater than 7. The addition of lime pyrite is inhibited.
The reason why lime inhibits pyrite is the formation of a hydrophilic film of Fe(OH)2 and Fe(OH)3 on the surface of the mineral.
Pyrite lime is suppressed, can be neutralized with sodium carbonate and copper sulphate, or sulfuric acid was added to the slurry was adjusted to a pH of 6-7, the flotation of pyrite can again.

Small Household Washing Machine

The small household Washing Machine is suitable for cleaning the small family yard. It can save time and effort to make your small yard clean, tidy and new.
There are some minor issues that need to be paid attention to in the process of using cold and hot water high-pressure cleaners, which are summarized as follows:
1. When operating the hot and Cold Water Pressure Washer: Always wear proper goggles, gloves and masks.
2. When the Spray Gun of the hot and cold water pressure washer is not used, the setting trigger must always be locked in a safe state.
3. Always check all the electrical connections of the hot and cold water pressure washer.
4. Frequently check all the hot and cold water high-pressure cleaner fluids.
5. Always keep hands and feet away from the cleaning nozzle.
6. Before disconnecting the hose, always release the pressure in the washing machine.
7. Always use low pressure to work as much as possible, but the pressure must be sufficient to complete the work.
8. Never start the equipment before turning on the water supply and allowing proper water to flow through the spray gun stem. Then connect the required cleaning nozzle to the spray gun stem
superior.
9. Always drain the water in the hose after each use.
