摘 要
选别石墨的方法有有重选、电选浮选这三种方法,用得最多的选矿方法是浮选。对国内外浮选石墨的工艺进行介绍,在浮选设备、浮选药剂以及保护石墨大晶片方面的一些工艺研究。根据矿山的石墨性质,结合当地的条件,确定了3万吨/年石墨精矿选矿厂的工艺流程。选矿厂的原矿品位α=3.19%,精矿品位β=93.89%,精矿总回收率ε=90.19%,精矿量3万吨,对石墨选矿厂进行设计。根据这些数据推出原矿的处理量,结合该选矿厂的工作制度,确定破碎车间和磨浮车间的日处理量。根据原矿的最大粒度,破碎之后的最大粒度,计算破碎比,确定选用三段一闭路的破碎流程,筛分之后细粒度的矿物进入磨浮车间,进行磨矿浮选。进入磨浮车间的矿物进行粗磨,粗磨之后粗选,如此重复选别五次。根据每天的处理量,计算各段的数质量以及水量和矿浆量,画出数质量流程图和水质量流程图,根据数质量流程图、水质量流程图以及各段选矿的产物的要求,比如磨矿细度,产率等来对磨机的磨矿时间以及浮选机的浮选时间进行判断,对设备的类型进行选择;根据各段的处理量,对各设备的型号和规格进行选择。 [资料来源:http://www.doc163.com]

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.Then according to the graphite nature, combined with the local conditions, 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, the graphite ore dressing plant design. 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.
Keywords: mineral processing design;graphite ore dressing;production process;equipment selection.
