Abstract relates to a brass ore leaching process of the invention, at a low temperature and pressure, using as a catalyst a silver salt, ammonium persulfate as the oxidant, oxidation of chalcopyrite leaching, controlling the temperature of 70-95 deg.] C, After leaching for 5-10 hours, a copper sulfate solution having a leaching rate of 96% or more and a copper recovery rate of 97% or more can be obtained. Since high temperature and high pressure are not required, the requirements for anti-corrosion and pressure of the equipment during leaching are not high, and the environment is not harmful. The silver salt used in the process is not lost. After the ammonium persulfate is regenerated, it can be recycled, and the production cost can be reduced. It can be seen that the invention is a method for leaching chalcopyrite with simple process flow, short production cycle, low production cost and high production efficiency.
Asphalt heating storage equipment is mainly composed of heating device, storage tank and control system. The heating unit uses oil or gas burners to transfer heat to the asphalt to heat it to the proper temperature. Storage tanks are large containers used to store heated asphalt, generally made of high-temperature resistant materials. The control system is responsible for monitoring the operating status of the equipment and the temperature of the asphalt to ensure the safe and stable operation of the equipment.
The heating principle of asphalt heating storage equipment is to transfer heat to asphalt through thermal conduction, so that it is heated. Heating devices are generally divided into direct heating and indirect heating in two ways. Direct heating is the use of the burner directly into the storage tank, hot air through the contact of hot air with the asphalt to heat it. Indirect heating is the use of heat exchangers to heat the asphalt in the storage tank without direct contact with the air. The two heating methods have advantages and disadvantages, and need to be selected according to the actual situation.
Asphalt heating storage equipment heating speed, can quickly heat asphalt to the use of temperature, improve production efficiency. At the same time, the equipment also has environmental protection characteristics, reducing exhaust gas and smoke emissions, reducing the impact on the environment. In addition, the operation of asphalt heating storage equipment is simple and easy to maintain, which can meet the needs of various road construction and maintenance projects.
In short, asphalt heating storage equipment is an important road construction equipment, with high efficiency, safety, environmental protection and other characteristics. It can provide a stable supply of asphalt for road construction, improve construction efficiency, reduce the impact on the environment and waste of resources. The equipment has a wide application prospect in the field of road construction.
