Abstract

The theoretical and experimental research is aimed to improve pretreatment and concentration of rebellious ore from the Rubtsovsk deposit. Radiation modification of lead–zinc ore properties stimulates milling efficiency and enhances processing efficiency. After radiation modification, percentage of free grains of galenite and wurtzite in milled product increased from 40.7 and 65.7% to 66.4 and 71.5%, respectively, in treatment by accelerated electrons at radiation dose of 5 kGr. As a result, the increment in zinc and lead recovery in rougher flotation concentrate made 4.74 and 9.50%, respectively.

通过矿物特性的辐射改性提高磨粉选择性和利用完整性

摘要

理论和实验研究旨在改进Rubtsovsk矿床叛逆矿石的预处理和浓缩。铅锌矿石性质的辐射改性可提高研磨效率并提高加工效率。辐射改性后，在辐射剂量为 5 kGr 的加速电子处理下，碾磨产品中方铅矿和纤锌矿的游离颗粒百分比分别从 40.7% 和 65.7% 增加到 66.4% 和 71.5%。因此，粗浮选精矿中锌和铅的回收率分别增加了 4.74% 和 9.50%。
