Re-election process and equipment

Environmental awareness has increased over the past 30 years. Cost and maximum recovery are no longer the only considerations for plant design. Efficient, efficient and environmentally acceptable processes, combined with an understanding of maximum recovery rates, do not necessarily lead to the best economic benefits that are considered today. Re-election is not limited by the coarseness of the particles. Assuming that the minerals are sufficiently dissociated, the tailings can be removed as coarse as possible, thus reducing the need for grinding energy. In addition, re-election does not require a drug. Since the tailings discharge and waste purification are simplified, not only the main cost is reduced, but also the environmental cost is reduced.

2.1 re-election process

The ore re-election process consists of a series of continuous operations. The nature of the work can be divided into three parts: preparation work, sorting work, and product handling work.

(1) Preparation, including a: crushing and grinding for dissociation of useful mineral monomers; b: multi-colloid or clay-containing ore for washing and de-slurry; c: screening or A method for hydraulic classification by size classification into mineral stone. The ore is selected separately after grading, which is beneficial to selecting operating conditions and improving sorting efficiency.

(2) The sorting operation is the main part of the ore sorting. The selection process is simple and complex, and consists of simple unit operations, such as heavy media sorting.

(3) Product handling operations, mainly refers to concentrate dewatering, tailings transportation and storage.

2.2 Reselection equipment

To handle modern minerals, the equipment required must have the following characteristics:

(1) The amount of processing is large, and modern mineral processing objectively requires the use of scale effects to create benefits.

(2) The effect on the fine grain size is remarkable, especially for the -01037mm grain size, and the original equipment can basically guarantee the recovery of the +01037mm grain size.

(3) The enrichment is relatively high and the selection index is good.

(4) Low power consumption.

(5) The structure is simple and easy to maintain.
