Abstract

The results of experimental modeling of the arsenic transition from natural arsenides to mobile oxidized species in the near-surface environment are discussed. The experiment has been carried out with the samples collected from the dump of the Schlema-Alberoda deposit. Arsenides (safflorite, löllingite, nickeline, rammelsbergite) have been dissolved in acidic and near-neutral oxidative media for a month. As a result, the new data on arsenic leaching capability in order to form new phases (annabergite, scorodite, and iron hydroxides) have been obtained.

摘要

讨论了在近地表环境中砷从天然砷化物向可移动的氧化物质过渡的实验模型化结果。实验是从Schlema-Alberoda矿场的垃圾场收集的样品进行的。砷化物（方镁石，硅镁石，镍，拉美铁矿）已在酸性和接近中性的氧化介质中溶解了一个月。结果，获得了有关砷浸出能力以形成新相（菱锰矿，臭葱石和氢氧化铁）的新数据。
