Abstract A solid waste sample from acidic leaching of Alluoga sedimentary rocks, SW Sinai, Egypt, was processed for and extraction U Cu respectively. This assayed 200 mg/kg 5 g/kg Cu. The present work aims to obtain free through selective alkaline uranium followed by environmentally safe glycine solution copper the resulted waste. Under studied optimum conditions efficiency attained 93% 96% Ura...

In 1938, Smoker proposed an analytical closed form formula to calculate the number of stages in a binary distillation column. The equation assumes constant relative volatility and constant molar overflow. For many mixtures, it is practical to assume constant relative volatility. However, the latent heat of vaporization of the different components are generally not equal and hence, the analytica...

− The present paper deals with the extractive separation and selective recovery of nickel and lithium from the sulfate leachate of cathode scrap generated during the manufacture of LIBs. The conditions for extraction, scrubbing and stripping of nickel from lithium were optimized with an aqueous feed containing 2.54 kg·m Ni and 4.82 kg·m Li using PC-88A. Over 99.6% nickel was extracted with 0.15...

The extraction behavior of Cu(II) ions from a real sulfate liquor obtained from the heap leaching stage of a copper oxide ore was investigated using a chelating reagent, Chemorex CP-150 in kerosene. A comparative study was also carried out on the extraction capability of Cu(II) ions using other solvents including D2EHPA and Cyanex 272.Chemorex CP-150 demonstrated an effective and selective extr...

Precious metals are currently associated with selenium (naumannite, Ag2Se) and tellurium (calaverite, AuTe2; sylvanite, (Au,Ag)2Te4) to form species refractory to cyanidation. The aim of this preliminary work was to study the use of the solvent extraction technique to recover tellurium and selenium ions from a synthetic solution similar to the cyanidation effluents to recycle the free cyanide b...

In this study the extractive capability of Mextral 5640H was investigated for extraction copper from a heap leach liquor. regard, influence parameters such as pH (0.2–2.8), extractant concentration in kerosene diluent (2.5%–10% v/v), temperature (25–70 °C), contact time (0–300 s), stirring speed (100–1200 rpm), phase ratio (O/A) (0.6–1.8) and Cu initial (0.5–2 g/L) liquor were examined optimize...

In this study, solvent extraction is applied for extracting nickel from sulfate solutions containing iron and cobalt ions. This process can also be the cleaning of waste increasing solution concentrations after leaching low-grade ores. Di-2-Ethylhexyl phosphoric acid (D2EHPA) was used as an extractant purpose. Effects pH, aqueous/organic (A/O) phase ratio, iron, ion contents on efficiency were ...

Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized. It was observed that copper was almost completely extracted into the organic phase compr...
