The leached acid cocktail is neutralized with sodium hydroxide, sodium bicarbonate is added and manganese carbonate, cobalt hydroxide and lithium bicarbonate are precipitated, with the respective necessary conditions. Then Evapo-crystallization of the precipitated products is carried out and recoveries greater than 96.0% are achieved in each metal.

Acid,, ,alkali, and soda ash are added as indicated, and the waste is detained in the retention tank under air pressure long enough to absorb quantities of air. Upon release through a pressure regulator valve into the air flotation unit the cracked soluble oil is floated to the top surface along with the minute floe quantities and swept into a sludge hold tank by scrappers or flight conveyors.

The best way to neutralize acid in wastewater is to dose with an alkali to maintain a neutral pH level. The traditional method to treat acidic wastewater involves the use of caustic soda, otherwise known as sodium hydroxide (NaOH). Other widely used alkalis are soda ash (sodium carbonate) or hydrated lime (calcium hydroxide).
