In a race to save the earth of its rapidly depleting natural resources, the use of Secondary
Raw Materials (SMRs) as alternative replacements in several processes is currently …

The recovery of zinc from a flotation tailing using 17-different leaching agents, including
inorganic and organic acids, alkaline solutions and chelating agents, was investigated. The …

The production of metallic copper from low-grade copper ores is generally carried out by
hydrometallurgical methods. Leaching is the first prerequisite of any hydrometallurgical …

Zinc is one of the most important metal required in metallurgical and chemical industries. As
the high-grade resources diminished, the treatment of processing plants tailings can be …

In the present study, a selective leaching process of zinc from a low-grade carbonate source
is proposed by the use of a green lixiviant, namely glycine. Response surface methodology …

The solutions containing ammonia allow for selective leaching of the copper from a copper
ore. In this study, the leaching and kinetics of malachite ore were examined using …

The recovery of zinc and lead from Yahyali non-sulphide flotation tailing using sulfuric acid
followed by sodium hydroxide leaching in the presence of potassium sodium tartrate was …

The Taguchi method was used as the experimental design to determine the optimum
conditions of purification behavior of the leach solution obtained from ammoniacal …

In this paper, a novel system for leaching of low-grade and multiphase zinc oxide ore is
presented, in which ammonia–ammonium sulfate is chosen as leaching agent, meanwhile …

Zinc filter cakes (ZFCs) have economic values as secondary sources, but also are classified
as hazardous waste and have negative effects on human health and the environment …
