2022.12.12 The weathering and leaching of mining tailings have released large amounts of antimony (Sb) and arsenic (As), causing serious pollution in the surrounding soil, water, and sediments. To understand the leaching characteristics of Sb and As in mining tailings, Zuoxiguo and Qinglong mining tailings were collected for analysis. The average

1989.1.1 Abstract. On the basis of knowledge of the beneficiation properties of antimony minerals reported in the previous part of this article, this second half reviews the state of technology for separation of those minerals and summarizes experience from processing plants. The high density of antimony minerals and their tendency to grind to

2022.1.16 Antimony leaching from tetrahedrite-bearing ores was typically carried out by using Na2S-NaOH solutions. In the current paper, the detail mechanism of antimony leaching from tetrahedrite-rich concentrate via K2S and BaS lixiviants was investigated for the first time. Sample was characterized in terms of chemical, mineralogical, and

2021.6.1 Introduction. Arsenic is widely associated with non-ferrous metal minerals (Tan et al., 2018). During the non-ferrous metal processing, most of arsenic is volatilized into the flue gas, and then further reacts with lead, antimony and zinc in high temperature gas to generate arsenate or arsenite, forming a high‑arsenic dust (HAD) with smaller particle
