Optimization method of grinding process of rock and gold ore selection plant

In the mineral processing process of rock gold mines, the grinding process plays an important role, affecting the recovery rate of gold and the grade of concentrate.With the further development of the mineral processing industry, traditional grinding processes and equipment have been unable to meet the increasing production needs of mineral processing plants.So how can we optimize the grinding process of the rock and gold mining plant?After reading this article, it may be able to give you some new inspiration.

The importance of grinding technology

The grinding process is the core link in the mineral processing process of rock and gold mines. Its purpose is to grind the ore to a certain particle size, so that the gold particles are fully dissociated, and create conditions for subsequent flotation or cyanidation processes.The level of grinding efficiency directly affects the cost and efficiency of the entire mineral processing process.

Optimized design of crushing and grinding process

The design of the crushing and grinding process of the rock and gold ore selection plant should follow the principle of “more crushing and less grinding”, and realize the high efficiency and energy saving of crushing and grinding operations through the use of new technologies, new processes, and new equipment.

1.Enhanced crushing process: On the basis of the conventional crushing process, a small-scale crusher can be added to supplement the coarse crushing of large ore blocks in the coarse crushing products, increase production capacity and reduce product particle size.

2.Application of high-efficiency and energy-saving equipment: use a new type of high-efficiency cone crusher to replace traditional equipment, reduce plant area and height difference requirements, shorten transformation time, and reduce infrastructure investment.

3.Optimization of self-grinding (semi-self-grinding) technology: For ores adapted to self-grinding, self-grinding open-circuit grinding and large-inclination spiral classifiers are used to simplify the process, save investment and reduce production costs.

Simplification and strengthening of grinding and grading process

1.Simplify the number of grinding segments: In the design of a small cyanide plant, a two-stage grading process for one-stage grinding is used to reduce the number of grinding segments while ensuring the fineness of the grinding.

2.Strengthen grading operations: improve the efficiency of grading equipment, use a new type of high-efficiency cyclone to replace the traditional spiral classifier, and realize the early sorting and tail-throwing of coarse grains.

3.Large-scale and automated grinding machines: large-scale ball milling systems and automated control technologies are used to accurately control the process conditions of the grinding process, improve the grinding efficiency and reduce costs.

Technological innovation of grinding technology

1.Self-grinding open-circuit grinding process: For small-scale mines, self-grinding machines are used for open-circuit grinding to simplify the process structure and reduce energy consumption.

2.Application of large-inclination spiral classifier: The application of large-inclination spiral classifier in the self-grinding circuit solves the problem of high-difference configuration, reduces the complexity of process layout, and improves production stability.

3.Screening instead of grading: In the grinding stage, fine screens are used instead of grading equipment to improve separation accuracy and screening efficiency.

The optimization of the grinding process of rock and gold ore selection plants is the key to improving production efficiency, reducing costs, and enhancing market competitiveness.Through the use of enhanced crushing process, high-efficiency and energy-saving equipment, self-grinding technology, simplified grinding grading process, and technological innovation, the optimization and upgrading of the grinding process can be realized.In the future, with the continuous progress and innovation of technology, the grinding process of rock and gold mining plants will be more efficient, environmentally friendly and intelligent.
