Abstract

The demand for environmental friendliness is increasing as the industrialized world progresses. Froth flotation is widely used in enrichment processes in the phosphate industry due to its low cost and simplicity of use. However, successful flotation processing requires several reagents, mostly synthetic chemicals commonly used in industry. To safeguard the environment, it is crucial to reconsider these chemicals, as their low degradability can harm water resources and human health. As a result, most researchers have paid attention to the flotation separation of phosphate ore using eco-friendly alternative reagents, including natural polymers, biosurfactants, and green chemicals. This review aims to present a comprehensive overview of the wide availability of eco-friendly reagents currently used in phosphate ore flotation. Additionally, the paper will examine the impact of these reagents on flotation performance, such as recovery rates and selectivity. Through this comprehensive analysis, we attempt to highlight the progress and challenges associated with the adoption of green reagents in the phosphate industry, thereby contributing to the development of more sustainable mineral processing practices.

磷矿浮选的现状和可持续发展途径：生态友好型药剂及其应用综述

随着工业化世界的发展，对环境友好的需求也在增加。泡沫浮选因其成本低、操作简单而广泛应用于磷酸盐工业的富集工艺中。然而，成功的浮选过程需要几种试剂，主要是工业上常用的合成化学品。为了保护环境，重新考虑这些化学物质是至关重要的，因为它们的低降解性会损害水资源和人类健康。因此，利用天然聚合物、生物表面活性剂、绿色化学剂等环保替代试剂进行磷矿浮选分离已成为研究热点。本文综述了目前磷矿浮选中广泛使用的环保试剂的概况。此外，本文将研究这些试剂对浮选性能的影响，如回收率和选择性。通过这一全面的分析，我们试图强调在磷酸盐工业中采用绿色试剂的进展和挑战，从而促进更可持续的矿物加工实践的发展。
