The solution, obtained during the HPAL process, which is rich in nickel and cobalt, is gradually purified from impurities by adjusting pH profile and transferred to the MPH unit. Magnesium oxide is added to reactors in the relevant unit and precipitated in the form of hydroxyl. Relevant sediment is transferred to condenser tanks with the aid of pumps to increase the density of the filter press feeding tanks. The high density MHP product obtained is dewatered through equipment such as filter presses. The rich concentrate of nickel and cobalt obtained is filled into bigbag bags and transported to the storage area.
