摘要： 采用一种经济优化分析方法,确定某赤铁矿的浮选精矿的最佳产率和品位,使其经济效益最大化.针对该赤铁矿,首先选用NaOH,淀粉,CaO,RA515作为反浮选药剂,并通过大量的浮选试验,确定各药剂的用量范围;然后通过正交试验建立了精矿品位、产率与各种浮选药剂用量之间的回归模型.根据精矿价格与品位的关系,建立优化模型,最终采用经济优化分析方法得出当浮选精矿品位和产率分别为61.95%和61.19%时,每百吨原矿收入达到6.9万元的最大值.实例验证了这种方法的简单和实用性.

Abstract: An economic optimization-oriented method of analysis was proposed to determine the optimal output rate and grade of flotation concentrate from a certain hematite mine, thus maximizing the economic benefit. With the NaOH, starch, CaO and RA515 used as reverse flotation agents and lots of flotation tests done, the allowable ranges of dose of different agents were determined, then a regression model was developed through orthogonal tests to determine the concentrate grade, output rate and dose of various agents for flotation. According to the relation between price and concentrate grade, an optimization model was developed and, as a result, the proposed method was used to determine the appropriate concentrate grade and output value, i.e., 61.95% and 61.19%, respectively, by which the max. income per 100 t raw ore came up to RMB 69 thousand yuan. Exemplification result showed that the method proposed is simple and practical.
