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.

Abstract: The disclosure discloses a method for preparing a battery-grade nickel-cobalt-manganese sulfate solution from low nickel matte.

Abstract: The invention discloses a method and a device, a storage medium and a processor for data acquisition and query, and relates to the technical field of computers, with a major object to ensure that at a front end, not only the times of clicks on and accesses to elements can be viewed, but also data of the associated elements can be displayed. The data acquisition method comprises: receiving custom data acquisition information; generating a first configuration file according to the custom data acquisition information; reading the first configuration file, acquiring monitored website data according to the first configuration file, sending the monitored website data to a server side, further defining the monitored website data according to path information corresponding to the acquired monitored website data to generate a second configuration file; and sending the second configuration file to a server so that the server generates query data according to the second configuration file.
