Complex sulfide ores are associated with various sulfide minerals, characterized by their impurity content and physical defects. Sphalerite, a well known Zn-bearing mineral, consists of sulfides and inevitably contains various impurities. In this regard, minor metals in Zn concentrate complicate the flotation process or hydrometallurgical process. Nevertheless, the Fe-containing sphalerite is regarded as an efficient inorganic co-catalyst due to its surface properties with unsaturated S atoms an
Permeable reactive barriers (PRBs) are passive and sustainable treatment systems for remediating the diffusion of contaminant plumes in groundwater. Several conventional reactive materials such as activated carbon (AC) have long been used as reactive media for PRBs. AC, which is known for its high adsorption capability and cost-effectiveness, is commonly used to remove multiple pollutants from groundwater. Unfortunately, among the reactive materials, AC can fill in the barrier and pose practical
Abstract Thermal treatment of mercury (Hg)-contaminated soil was studied to investigate the desorption behavior of Hg at different temperatures. The soil samples were collected from two locations with different land uses around the mine and industrial site. The effect of soil properties such as inorganic carbonate minerals and organic matter content on Hg desorption was investigated to understand the thermal desorption process. The effect of soil composition on Hg desorption showed that behavior
