HIGH-PRESSURE REACTOR ACID ADDING SYSTEM FOR LATERITE NICKEL ORE HYDROMETALLURGY

Abstract: a high-pressure reactor acid adding system for laterite nickel ore hydrometallurgy includes: an acid liquor supply tank, an acid adding pipe, an acid adding pump, a pressure stabilizer, and a high-pressure reaction kettle, where one end of the acid adding pipe is communicated with the high-pressure reaction kettle, the other end thereof is communicated with the acid liquor supply tank, and the acid adding pump is disposed on the acid adding pipe and is configured to pressurize and pump acid liquor in the acid liquor supply tank to the high-pressure reaction kettle through the acid adding pipe; and the pressure stabilizer is disposed on the acid adding pipe and is configured to dynamically accommodate or discharge the acid liquor, to reduce pressure fluctuation in the acid adding pipe. compared with the prior art, according to this disclosure, the pressure stabilizer is disposed on the acid adding pipe.
