中文摘要: 云南磷化集团有限公司A矿区产的硅酸盐型胶磷矿的SiO2含量一般在30%以上,堆存数量巨大,使用常规的单反浮选工艺难以达到要求的精矿指标,但是使用正反浮选工艺或者双反浮选工艺的生产成本又较高,经济效益不理想。本文从矿石的多元素进行研究分析,发现与CaO/P2O5大于1.79的碳酸型磷块岩配矿后使用单反浮选工艺可以获得合格的精矿指标。在此思路上,对两种矿石进行配合比、解离度、磨矿细度和药剂制度进行探索研究。在配合比为1:3,磨矿细度为92%,药剂制度为抑制剂1.5kg/t,调整剂18kg/t,捕收剂3.0kg/t的情况下,最终可以获得P2O5品位为28.89%,MgO品位为0.91%,产率62.73%,回收率85.24%的精矿指标。

Abstract:The SiO2 content of silicate colloidal phosphate ore produced in A mining area of A company is generally more than 30%, the amount of storage is huge, the conventional single reverse flotation process is difficult to achieve the required concentrate index, but the production cost of using the positive reverse flotation process or the double reverse flotation process is relatively high, and the economic benefit is not ideal. In this paper, through the study and analysis of the multiple elements of ore, it is found that the qualified concentrate fingers can be obtained by the single reverse flotation process after the ore blending with CaO/P2O5, which is larger than 1.79. In this way, the mixture ratio, dissociation degree, grinding fineness and reagent system of two ores were studied. Finally, the concentrate indicators of P2O5 (28.89%), MgO (0.91%), yield (62.73%) and recovery (85.24%) were determined when the mixture ratio was 1:3, grinding fineness (92%), pharmaceutical system (1.5kg/t), regulator (18kg/t) and collector (3.0kg/t).
