摘要

浮选是一种广泛应用的精煤选矿技术,特别是粒度小于 0.5 毫米的精煤。在这项研究中,使用释放分析技术分析了中央煤田有限公司(CCL)的卡尔玛煤样的浮选性能。实验样品的粒度范围为 - 0.15 至 + 0.074 毫米。修改了各种操作参数,如捕收剂用量(千克/吨)、泡沫剂用量(千克/吨)和矿浆密度(%),以评估它们对浮选性能的影响。绘制了释放曲线,以确定不同操作参数下的累积产品百分比和产品灰分百分比。柴油和松油的用量分别为 0.75 千克/吨和 0.5 千克/吨时,获得的最高产率为 92.33%。在纸浆密度为 15%的情况下,灰分含量为 30.65%。相反,使用单一的 MIBC 发泡剂(用量为 0.15 千克/吨)得到的产量最低,为 53.26%。

Release Analysis by Combining Different Reagents and Choosing Best Reagent in Batch Type Froth Flotation Process for Central Coalfields Limited (CCL) Karma Coal

Froth flotation is a widely used technique for the beneficiation of fine coals, specifically those whose size less than 0.5 mm. In this study, the flotation performance of Karma coal samples from Central Coalfields Limited (CCL) was analysed using the release analysis technique. The experimental samples had a size range of − 0.15 to + 0.074 mm. Various operational parameters such as collector dosage (kg/tonne), frother dosage (kg/tonne), and pulp density (%) were modified to assess their impact on flotation performance. Release curves were plotted to determine the cumulative product percentage and the product ash percentage for different operating parameters. The highest yield achieved was 92.33% with a combination of diesel oil and pine oil at dosages of 0.75 kg/tonne and 0.5 kg/tonne, respectively. This yield had an ash level of 30.65% at a pulp density of 15%. Conversely, the lowest yield of 53.26% was obtained using a single MIBC frother at a dosage of 0.15 kg/tonne.
