A pre-feasibility study has been completed to test the viability of recovering a magnesium hydroxide (Mg(OH)2) from the tailings material through construction of this 7 500 tpm on-site plant. The processing facility will initially utilise 3 500 tons of sulphuric acid per month to treat the magnesium silicate produced at Kobolondo. This results in the production of 2 100 tons of magnesium hydroxide per month.
The plant consists of batch leaching, batch precipitation, batch neutralisation, batch filtration and drying circuits, which can produce magnesium sulphate or hydroxide.
Coarse fraction chrysotile tailings will be deposited on a newly constructed stockpile adjacent to the processing plant.
