Abstract Sulfuric acid leaching process was applied to extracting rare earth (RE) from roasted ore of Dechang bastnaesite in Sichuan China The effect of particle size stirring speed sulfuric acid concentration and leaching temperature on RE extraction efficiency was investigated and the leaching kinetics of RE was analyzed

Column leaching test was carried out for uranium ore samples obtained from a uranium in-situ leaching (ISL) mining site using 2 45 bed volumes (BVs) of 0 255 M sulphuric acid to study the evolution of uranium concentration and its isotopic 234 U/ 238 U activity ratio in the pregnant leach solution The activity ratio of the two uranium isotopes in the pregnant leach solution was measured by

Impact of simulated acid rain on trace metals and

This study investigated the impacts of simulated acid rain (SAR) upon leaching of trace metals and aluminum (Al) from a soil Soil pot leaching experiments were performed to investigate the impacts of SAR at five different pH levels (or treatments) over a 34-day period upon the release of trace metals (i e Cu Ni Pb Zn and Fe) and Al from the Latosol (acidic red soil)

Mine wastes should be flooded before they become acid generating or metal leaching otherwise some metals and acid will dissolve into the water and this will have to be managed Although flooding can effectively prevent sulphide oxidation and the acid generation process there can sometimes be residual metal leaching issues

Speciation of the sulfuric acid-ferric sulfate-ferrous sulfate-water system and its application to chalcopyrite leaching kinetics up to 150 C Creator Yue Guikuan Publisher University of British Columbia Date Issued 2015 Description Hydrometallurgical oxidation methods are increasingly being considered for the extraction of Cu from

In this work the ore material was subjected to sulfuric acid leaching in the presence of oxalic acid as a reductant to maximize the extraction of Mn The optimum leaching conditions to achieve almost complete leaching efficiency of Mn with Fe dissolution not exceeding 13% involved 0 5 M sulfuric acid and 0 25 M oxalic acid in a solid/liquid ratio of 1/15 at 85C for 105 min using an ore size

24 01 1978A process of leaching silicated zinc ore with sulfuric acid comprising the steps of reacting silicated zinc ore with at least a stoichiometric amount of a 1N to 6N sulfuric acid solution near its boiling point until a gelatinous mass is formed containing hydrated silica and zinc sulfate evaporating at least 60% of the water content of the gelatinous mass so that substantially all the silica

Sulfuric acid leaching circuits commonly employ either manganese dioxide or chlorate ion to oxidize the tetravalent uranium ion (U 4+) to the hexavalent uranyl ion (UO 2 2+) Typically about 5 kilograms (11 pounds) of manganese dioxide or 1 5 kilograms of sodium chlorate per
