Embodiment 1

[0027] The present invention comprehensively reclaims the processing method of high manganese cobalt ore, and is made up of following processing steps:

[0028] (1) Reductive leaching step: put 1000 grams of cobalt ore crushed to 150 microns and 22% manganese into clear water at a liquid-solid weight ratio of 3:1, stir to form a slurry, and The temperature of the slurry is raised to 50°C, and then 220 grams of sodium thiosulfate and 396 grams of concentrated sulfuric acid are slowly added at the same time. The reduction leaching reaction time is controlled at about 4 hours, and the pH is always controlled during the reaction process. After the reaction is completed, filter to obtain the filtrate As a backup, the filtrate contains valuable metal ions: Mn 2+ 、Co 2+ 、Ni 2+ 、Cu 2+ and impurity metal ions: Fe 3+ , Zn 2+ 、Al 3+ , Mg 2+ , Ca 2+ 、Na + etc., discard the filter residue;

[0029] (2) preliminary purification step: the standby filtrate of step (1) gained is tran...

Abstract

The invention discloses a processing method for comprehensively recovering high manganese asbolite, belonging to the field of hydrometallurgy. In the processing method, the high manganese asbolite is processed through four processing steps comprising (1) reduction leaching, (2) primary cleaning, (3) manganese and cobalt separation and (4) extraction separation to obtain a product manganese carbonate, copper sulfate, nickel carbonate or cobaltous sulfate. The processing method has the advantages that the source of raw materials is wide, the process and equipment are simple, the operation is stable, the energy consumption is low, the production cost is low, the practicability is wide, and the economic effect and the society effect are obvious.

Description

technical field [0001] The invention belongs to the field of hydrometallurgy, and in particular relates to a treatment method for comprehensive recovery of high manganese cobalt ore. Background technique [0002] Cobalt ore in Hainan is a dark brown flake or strip oxide ore. Its mineral composition is mainly manganese ore, limonite and gibbsite. In addition to cobalt, the minerals also contain manganese, nickel, Valuable metals such as copper, except Fe, Ca, Mg, Si, the total amount of valuable metals is more than 30%, and the weight ratio of manganese to cobalt is ≥20. Therefore, this is a typical high manganese cobalt ore. The cobalt in this ore is mainly mixed into duromanganese ore in the form of isomorphism; secondly, it is distributed in limonite, kaolinite, and chlorite, and small particles of pyrolusite are distributed near the cracks and edges of duromanganese ore. The content in manganese ore is significantly lower than that in hard manganese ore, and nickel and ...
