TL;DR: In this review, the background, concepts and applications of phytoremediation are comprehensively discussed, and proper amendments used to improve the physical, chemical and biological properties of mine tailings are systematically reviewed and compared.

TL;DR: In this article, a new collector, lead complexes of benzohydroxamic acid, was found to be selective for the separation of scheelite and calcium minerals with little water glass, and a novel flotation process was developed for the recovery of tungsten minerals in Shizhuyuan Mine in China.

TL;DR: In this article, the effect of Fe3+ ions as an activator on the flotation performance of cassiterite using benzohydroxamic acid (BHA) as the collector was investigated by the micro-flotation tests.

TL;DR: An extensive review of the previous restoration techniques and the challenges encountered during the restoration of mine tailings is highlighted to act as a valuable reference for the researchers involved in mine tailing restoration.

TL;DR: In this paper, the authors reviewed the beneficiation technology and mechanism of feldspar proposed in the literature to identify the important parameters of the process and suggested that crystal structure, monovalent salts, flotation reagents, and particle size distribution are important factors in the process Environmentally-friendly principle and economic viability of various methods are discussed, and potential technologies are suggested Mixed cationic/anionic collectors appear to be a promising method for feld'spar flotation.
