Transformation method for multi-metal ore dressing, grinding and classification process

Abstract

The invention discloses a transformation method for a multi-metal ore dressing, grinding and classification process, and relates to the technical field of multi-metal ore dressing, grinding and classification process transformation, in particular to the transformation method for the multi-metal ore dressing, grinding and classification process. The transformation method comprises the following steps that S1, sample source arrangement and sampling re carried out before and after transformation; S2, the current situation of the grinding and classification process is analyzed; S3, grinding and classification transformation theoretical analysis is carried out; and S4, a grinding and classification transformation industrial test is carried out. According to the transformation method for the multi-metal ore dressing, grinding and classification process, after grinding and transformation method process transformation, on the premise that the processing capacity of a ball mill is kept, the total power of an ore mill is reduced by 120 kw, the reduction amplitude is 9.49%, and the total processing capacity of the ore mill, the total utilization coefficient of a first-stage ore mill, the total newly-generated minus 74 micrometer yield of the first-stage ore mill, the total utilization coefficient of a second-stage ore mill and the total newly-generated minus 74 micrometer yield of the second-stage ore mill are improved by 0.29%, 26.44%, 0.51%, 30.68% and 10.47% respectively.

Description

technical field [0001] The invention relates to the technical field of polymetallic beneficiation, grinding and grading, in particular to a process modification method for polymetallic beneficiation, grinding and grading. Background technique [0002] Grinding and classifying operations play an important role in the mineral processing plant. The investment in grinding and classifying equipment accounts for about 40% to 50% of the total investment of the entire mineral processing plant, and its energy consumption accounts for about 50% to 60% of the entire mineral processing production process. Grinding and grading are two complementary tasks. The quality of the grading effect directly affects the indicators of the grinding products, and the quality of the grinding will also affect the indicators of the grading products. Only when the two tasks are coordinated can the dressing plant bring The maximum benefit, so as to improve the work efficiency of grinding and classification...
