Abstract
In this paper, the method of flotation of graphite made brief introduction, gravity separation, electrostatic separation, flotation of the three methods, of course, now used up is flotation. The technology of flotation graphite at home and abroad is introduced, and some process of flotation equipment, flotation reagents and the protection of graphite chips. Refer to the relevant information according to the properties of the graphite and the conditions given, the technological process of the 10,000 tons / year graphite concentrate concentrator. The ore grade taste alpha is 3.19%, the concentrate taste beta is 93.89%, the total recovery rate of epsilon is 90.19% and the amount of concentrate is 10,000tons, and design of mineral processing production line of graphite concentrate.Launch the handling capacity of ore based on these data, combined with the concentrator of the system and determining the amount of daily processing of crushing and grinding and flotation workshop for workshop. First according to the maximum particle size of the ore, and after the crushing of the maximum particle size calculated broken ratio, determine the selection of three sections of a closed-circuit crushing process, the screening fine-grained minerals into grinding and flotation workshop, grinding flotation. Enter the floating mill workshop first minerals for coarse grinding, coarse grinding after roughing, after regrinding, a total of five times. According to the daily handling capacity, sections of the quantity and quality, the water quantity and pulp volume was calculated and draw the flow chart of the number of quality and the quality of the water flow chart, according to the flow chart of the number of quality, water quality, flow chart and segment processing product requirements, such as grinding fineness and yield of the mill grinding ore time as well as the flotation machine flotation time to judge, and the equipment type selection; according to the processing capacity of the paragraphs, the equipment models and specifications.
