Recovery of nickel from lateritic nickel ore using

2009-2-1  A. niger was grown in presence of ore and produces acids to dissolve the mineral, and referred to as indirect leaching. Leaching experiments were carried out in 250. ml Erlenmeyer flasks containing sterilized 100 ml MSM and sterilized adapted ore (ranging between 5% and 20%) with addition of 5–12.5% sucrose.. The pH of the media was adjusted at 6.8 with 1 N NaOH.
