Binhai Gold Mine Beneficiation Production Line

The coastal gold mine is one of the important gold resources in China, and its beneficiation production line is an important equipment for extracting gold ore. This article will introduce the operation steps and precautions of the ore dressing production line at the seaside gold mine.

1、 Operation steps of the ore dressing production line at the seaside gold mine

1. Ore crushing

Firstly, the ore extracted from the mine is sent to the crushing system of the beneficiation production line for crushing. The crushing system mainly consists of jaw crushers, cone crushers, impact crushers, etc. After crushing, the particle size of the ore will become finer, laying the foundation for the subsequent beneficiation process.

2. Ore grinding

ore grinding is the process of finely grinding the ore, with the aim of separating the metal minerals from the ore. The main equipment used for ore grinding is ball mills and mineral flotation machines. A ball mill is a process of placing ore into a mill and grinding it into smaller particles through the rolling and friction of the grinding balls. The mineral flotation machine suspends the ground ore in water and floats metal minerals through the action of bubbles, thereby achieving mineral separation.

3. Ore leaching

Ore leaching is the process of dissolving metal minerals from the ore. The main methods for ore leaching are cyanide leaching and sulfuric acid leaching. The cyanide leaching method involves placing the ore into a cyanide solution, which reacts with metal minerals to dissolve them. The sulfuric acid leaching method involves placing ore in a sulfuric acid solution, where sulfuric acid reacts with metal minerals to dissolve them.

4. Metal precipitation

Metal precipitation is the process of precipitating metal minerals dissolved in a solution. The main methods used for metal precipitation are zinc powder replacement and electrowinning. The zinc powder replacement method involves placing zinc powder in a solution, and metal minerals react with the zinc powder to precipitate it. The law of electrowinning is to precipitate metal minerals through electrolysis.

5. Metal melting

Metal smelting is the process of melting precipitated metal minerals. The main methods used for metal melting are electric furnace melting and furnace melting. The electric furnace melting method involves melting metal minerals into an electric furnace. The law of furnace melting is to put metal minerals into a furnace for melting.

2、 Precautions for the beneficiation production line of seaside gold mines

During the ore crushing process, attention should be paid to maintaining the normal operation of the crusher to avoid malfunctions.

2. During the ore grinding process, attention should be paid to controlling the speed of the mill to avoid uneven rolling of the grinding ball caused by excessive speed of the mill.

During the ore leaching process, attention should be paid to controlling the concentration of the solution to avoid affecting the leaching effect if the concentration is too high or too low.

4. During the metal precipitation process, attention should be paid to selecting suitable displacement or electrolysis agents to avoid poor precipitation effects.

5. During the metal smelting process, attention should be paid to controlling the furnace temperature to avoid affecting the smelting effect if the furnace temperature is too high or too low.

3、 Summary

The beneficiation production line of the seaside gold mine is an important equipment for extracting gold, and its operating steps include ore crushing, ore grinding, ore leaching, metal precipitation, and metal smelting. During the operation process, it is necessary to pay attention to maintaining the normal operation of the equipment, controlling the parameters of each link, and avoiding faults or affecting the extraction effect.
