Leaching occurs in metals recovery, in contaminated soil washing, and in many natural processes, such as fertilizer dissolution and rock weathering. This paper presents a model developed to simulate ...

Understanding the leaching behavior of arsenic (As) and selenium (Se) in coal fly ash is important in evaluating the potential environmental impact of coal fly ash. Batch experiments were employed to ...

Hydrometallurgy is a widely studied recovery process to recover NiMH battery, but the large chemical consumption restricted its application in industry. To achieve a low chemical consumption recovery ...
