Treatment system for the slag phase after removing iron-aluminum-chromium from leaching solution of laterite nickel ore

A treatment system for slag phase after removing iron-aluminum-chromium from leaching solution of laterite nickel ore, comprising:

• a filtering module, which comprises a material suction component and a filtering assembly;
• the material suction component is positioned within a slag phase sedimentation zone of a multi-stage removing iron-aluminum-chromium unit, with its material suction inlet connected to the slag phase sedimentation zone, for extracting the slag phase generated within the multi-stage removing iron-aluminum-chromium unit;
• wherein the slag phase includes iron, aluminum, cobalt, nickel, chromium, and manganese;
• the filtering assembly is connected to an outlet of the material suction component and is used to filter the slag phase;
• the filtering assembly has a filter residue outlet and a filtrate outlet that connects to the multi-stage removing iron-aluminum-chromium unit;
• a refining module, which is connected to the filter residue outlet and is used for crushing the filter residue;
• and,
• a feeding module, which comprises a material pipe and a material guiding drive component;
• the material pipe has a feed inlet connected to an outlet of the refining module and a discharge outlet connected to a neutralization unit for cyclic leaching ore pulp;
• the material guiding drive component is located inside the material pipe and is used to convey the slag phase into the neutralization unit for cyclic leaching ore pulp.
