Abstract

The influence of four factors—the reagent consumption, the pulp density, the content of fine slurry in the coal pulp, and the flotation time—on the flotation of coal fines at MMK-Ugol is studied by means of a full factorial experiment. First-order regression equations are obtained by simulation; the response functions selected in these equations are the total yield of concentrate, its ash content, the extraction of combustible mass in the concentrate, and the selectivity of the flotation process (including a set of flotation characteristics for coal fines). These formulas not only permit prediction of the enrichment results for coal with a high quantity of fine slurry but also permit management of the flotation process.

细浆含量高的煤浮选富集动力学

摘要

通过全因子试验研究了药剂用量、矿浆密度、煤浆中细浆含量和浮选时间四个因素对MMK-Ugol煤粉浮选的影响。模拟得到一阶回归方程；在这些方程中选择的响应函数是精矿的总产量、其灰分含量、精矿中可燃物质的提取以及浮选过程的选择性（包括一组煤粉的浮选特性）。这些公式不仅可以预测含有大量细浆的煤的富集结果，还可以对浮选过程进行管理。
