摘要:
我国原生金红石矿具有矿物成分复杂、目的矿物品位低、嵌布粒度较细等特点, 浮选法是回收利用金红石和提高其品位的重要手段, 其中浮选药剂是关键。浮选金红石的捕收剂主要有脂肪酸类、膦酸类、胂酸类、羟肟酸类, 调整剂可分为活化剂与抑制剂。为促进金红石选矿技术的进步, 以及为选矿工作者们提供技术理论的参考, 文章在概述了金红石矿性质、浮选难点以及微纳气泡浮选的基础上, 对捕收剂、抑制剂、活化剂的研究进展与作用机理进行了详细的阐述, 以加深对原生金红石矿浮选药剂的认识与了解, 并对未来药剂的研究方向进行了展望。
Abstract:Primary rutile ore in China has the characteristics of complex mineral composition, low grade of target mineral and fine disseminated grain size. Flotation is an important means of recovering and utilizing rutile and improving its grade, among which flotation reagent is the key. The collectors of flotation rutile mainly include fatty acid, phosphonic acid, arsine acid and hydroxamic acid, and the regulator can be divided into activator and inhibitor. To promote the progress of rutile mineral processing technology, as well as the theory of ore dressing workers to provide technical reference, based on the overview of the rutile ore properties, micro-nano flotation and flotation difficulties, the research progress and action mechanism of collectors, inhibitors and activators were summarized in detail to deepen the understanding of primary rutile flotation reagents, and the future research directions of reagents were also prospected.
