Abstract

Remaining Processing Results is a combination of grains measuring 0.001-0.6 mm and still has an economical concentrate content. Humphrey Spiral contained in PT Bumako produces cassiterite concentrate content of 2%, while the company's target concentration is 10%. So, a research was conducted on the Humphrey Spiral on a laboratory scale to determine changes in concentrate levels and cassiterite recovery, with flow rate parameters with variations of 1.017 m/s, 1.097 m/s and 1.172 m/s and feed sizes, namely 60 mesh, 80 mesh and 100 mesh. This research method uses Grain Counting Analysis (GCA) and XRF. Based on the results of the study, the accompanying minerals in the Humphrey Spiral bait consisted of 83.98% quartz, 5.65% limonite, 5.19% hematite, 2.83% iron oxide, 1.73% monazite, 0.34% chalcopyrite, magnetite 0.17% and muscovite 0.10%. The highest concentration gain and concentrate recovery was at a speed of 1.097 m/s at a grain size of 100 mesh with a content of 10.3788% and a high recovery of 44.1512%.

影响径流速度和饲料大小与Humprey螺旋处理在一个海湾区的规模

剩余的加工结果是0.001-0.6 mm的颗粒组合，仍然具有经济的精矿含量。PT Bumako中含有的Humphrey螺旋产生的锡石精矿含量为2%，而公司的目标浓度为10%。因此，在实验室规模上对Humphrey螺旋矿进行了研究，确定了流量参数分别为1.017 m/s、1.097 m/s和1.172 m/s，进料粒度分别为60目、80目和100目时，精矿水平和锡石回收率的变化情况。该研究方法采用了谷物计数分析(GCA)和XRF。研究结果表明，汉弗莱螺旋饵中伴生矿物为石英83.98%、褐铁矿5.65%、赤铁矿5.19%、氧化铁2.83%、独居石1.73%、黄铜矿0.34%、磁铁矿0.17%、白云母0.10%。在粒度为100目、含量为10.3788%、回收率为44.1512%的条件下，速度为1.097 m/s，精矿的富集率和回收率最高。

期刊介绍： Mineral Economics – Raw Materials Report is an international multidisciplinary journal focused on economics and policy issues in the minerals metals and mining industries. The journal exists to improve the understanding of economic social environmental and political implications of natural resources. The main focus is on non-fuel minerals metals and the mining industry and its role in society.Mineral Economics is widening its scope and particularly invites papers on: Socio-economic aspects of mining e.g. social license to operate indigenous peoples theory of change Materials for the Green transition e.g. battery metals ICT elements policies to secure supply of these elements Minerals in the periphery e.g. the Arctic deep-seabed and space Mineral Economics serves as a platform for academics industry practitioners decision makers and other experts who want to share perspectives and knowledge about natural resources.A wide range of topics have traditionally been covered including among others: mineral market analysis exploration and development resource availability market development price formation international trade environmental policy sustainability issues competition issues.Mineral Economics is a joint project of Lule? University of Technology and R?varugruppen Ekonomisk F?rening the organization which founded the journal Raw Materials Report in 1981
