Hydrometallurgical approaches have been successfully employed for metal separation and
recovery from various types of waste materials. Therefore, hydrometallurgy is a promising …

Hazardous waste (HW) management is challenging because of their extreme toxicity to the
environment and human beings. In the meantime, the occurrence of safety incidents that is …

This paper discusses the utilization of iron ore tailing aggregates (IOTA) as a replacement
for normal aggregates (NA) in dam concrete for hydraulic engineering applications. The …

In this study, microbial induce carbonate precipitation (MICP) was introduced to immobilize
chromium (Cr) in stainless steel pickling sludge (SSPS). Two methods were utilized to …

The pickling sludge produced from rolling process contains a large amount of Fe, Ca, Al as
well as other metals. If these metals can be extracted and used, it will promote the recycling …

Pickling sludge (PS) and presintered waste (PW) are two special steel solid wastes that
have potential as oxygen carriers due to their Fe content. Using these raw materials to …

Stainless-steel pickling sludge (SSPS) is a hazardous solid waste, which mainly contains
CaSO 4, CaF 2 and a high level of metals such as Fe, Cr and Ni. The high-content of sulfur …

It is vital for the development and application of heavy metal stabilization/solidification (S/S)
agents to reveal the mechanism of the reaction between water-soluble thiourea …

The present study investigated the preparation of nitric acid modified powder activated
carbon (MPAC) and its adsorption of trace amounts of Ni (II) from aqueous solution. Results …

Industrial wastewater sludge is one of the vital sources of metals, including heavy metals,
valuable metals, and precise metals. Apart from metals' necessity and economic value …
