In lixiviation circuits, where acid is used to dissolve valuable minerals and separate them from the gangue or waste, the pH of the application is usually between 2 and 3, or even lower.
Besides the acidity, these mixtures also contain abrasive solids remaining from the process, making it a complicated mixture to pump with standard equipment, presenting both abrasion and corrosion components.
Tecamyser® Dragflow acid-proof pumps are made in CD3MN duplex stainless steel in order to provide the best resistance to both risk factors. This duplex alloy has a far better corrosion resistance than the more common CD4MCu. This addition to our range allows us to operate in virtually any application out there.
