Bauxite Automatically Processing Plant

Bauxite Automatically Processing Plant

In China, bauxite is rich in resources but of relatively low quality. To choose valuable mineral bauxite, aluminum, we need to dress. However, a large number of tailings can also be produced in the process of ore dressing. If the tailings are discarded directly, it will often cause environmental pollution and waste of resources. Therefore, how to rationally use bauxite tailings has become a topic worth discussing. Bauxite automatically processing by changing the surface properties of the ore, it has floated, and then the purpose of the separation of the mineral and coal gangue. Finishing production line usually includes the main processes of crushing, grinding and floatation, and the key equipment is ball mill and floatation machine.

According to the characteristics of technical analysis of bauxite ore, the dissociation technology of dry and wet ores is selected, which can not only ensure better ore dissociation, but also save investment and reduce grinding cost. Rapid micro-bubble flotation selection of comprehensive flotation technology completely overcomes the technical difficulties existing in the automatic bauxite processing plant. The flotation gradient flotation process carries out A/S higher in coarse tailings for the refractory ore, separation, re-grinding and dissociation, and then the fine mineral is flotation separately to improve the overall recovery rate and alumina. The fine slurry is filtered by direct pressure and the tail slurry is concentrated by pressure filtration. Tailings go directly into steam curing and do not burn; Production without waste discharge.

Plant crushing and grinding principle of bauxite automatic processing shows that strengthening the reasonable crushing and reducing the particle size into the grinding machine is an important way to improve the grinding efficiency and reduce the mineral processing cost. The grinding efficiency is only 1%, and the crushing efficiency is up to 10%. Compared with the grinder, the crusher has low energy consumption and simple operation and maintenance. Therefore, after 50 years of practice and summary by crushing and grinding energy consumption and utilization, the cost of capital difference and mill different aspects such as the costs and benefits of different size and different levels of crushing and grinding research and analysis and comparison, the grinding field advocates "more crushing and less grinding" process broken new ground, namely reduce the dimensions of the crushing of the final product, increase the amount of fine particles in the product of crushing, so as to improve the processing capacity of mill, reduce the crushing capacity of grinding and metal consumption, reduce costs, improve economic efficiency, enhance the enterprise market competitiveness.

Our flotation machine on the basis of structural parameters and operating parameters bauxite automatically processing plant conducted a series of optimization improvements, successfully developed specifically for bauxite automatically processing plant bauxite beneficiation process characteristics of the new float upright choice sorter. Later, after many years of trial and practice developed specifically suited for bauxite flotation machine choose another joint unit to solve the low presence of Al-Si ratio of bauxite sorting equipment selection of technical problems, and obtained success Applications for the domestic bauxite processing plant has brought huge economic benefits.
