Abstract
A method for dynamically controlling high-pressure leaching reaction condition of laterite nickel ore includes: setting a target temperature and a target pressure of an high-pressure reactor; obtaining the heat power required for heating the feeding pulp to the target temperature; obtaining the heat power brought by the acid; obtaining the required new steam thermal power; obtaining the required new steam flow; adjusting the real-time flow of the new steam to the required flow of the new steam, and adjusting the exhaust valve opening degree and discharge flow rate of the high-pressure reactor to make the real-time pressure of the high-pressure reactor equal to the target pressure, and adjusting the flow rate of the new steam to make the real-time temperature of the high-pressure reactor equal to the target temperature.
