The dissolution of mno 2 from manganese nodules is possible by aleaching processthat works at low potential values using a reducing agent randhawa et al 2016 such as coal kanungo and das
Jul 10 2017 one example of aleaching processthat uses vatleachingis gold cyanidation theprocessof extracting gold from lowgrade ores in thisprocess a dilute solution of sodium cyanide nacn is used toleachthe au into solution the concentration is usually 001005 cyanide or 100500ppm
In the agglomeration stageorefines are fed into an agglomerator akaoredrum where they are tumbled with the leachate solution to cause theorefines to be more uniform in shape and size allowing the leachate to more effectively percolate through the heap and jumpstart theleaching process
Moreover ph temperature time and the amount ofironpowder were factors which were tested for copper cementation optimum conditions ofleachingstudies with 9911 recovery rate wereobtainedafter 120 grams per liter of h2so4 80 degrees celsius 2 hours and 100 grams per liter of solid to liquid
To keep enoughironin solution the chemical oxidation of metal sulfides must occur in an acid environment below ph 50 the ferrousironarising in this reaction can be reoxidized to ferricironby t ferrooxidans or l ferrooxidans and as such can take part in the oxidationprocessagain in indirectleachingthe bacteria do not need to be in contact with the mineral surface
A zincleachingefficiency of 967 wasobtainedunder theleachingconditions used aleachingtemperature of 55 c aleachingtime of 90 min a sulfuric acid dosage of 20 a sulfurous acid dosage of 4 a cinder particle size of 03 mm and a solidliquid ratio of r 14 after the gravity shakingtable separation a lead concentrate
The results ofleachinginvestigations showed that the particle size and sulfuric acid concentration also have significant effects on the recovery of zincironand copper iii the optimumleachingconditions to themaximumextraction of zn fe and cu from the residue occur at temperatureleaching85 c h2so4 concentration 2moll particle
The concentration ofironiii in theleachingsolutions was further varied to study the influence of the amount of oxidizing agent on theleachingefficiencyfig 4 shows that hardly was any copper leached with 01 mol l 1 of fecl 3 in eg with more fecl 3 present in theleachingsolution more copper andironwere dissolved theleachingpercentage of copper increased to 80 with 05 mol
A key step is the separation and concentration of the nickel in theleachliquor 15 gl from magnesium andorironto a tenor compatible with electrowinning or hydrogen pressure reduction
The present invention embodies aprocessfor extraction of nickel cobalt and other metals from laterite ores by heapleaching and of the productobtainedas well characterized by the fact that it is comprised of crushing i agglomeration ii stacking iii and heapleachingiv stages with this last stage being a continuous countercurrent heapleachingsystem with two or more
