Abstract

The invention discloses a treatment method of high-sediment carnallite raw ore. The method comprises the following steps that a brine supply device supplies saturated brine, a raw material supply device supplies a mixture containing sediment and carnallite raw ore, and the saturated brine and the mixture are stirred in a raw ore re-pulping device, so that the silt and the carnallite raw ore are dispersed in a liquid phase to form mixed ore pulp; the mixed ore pulp enters a raw ore separation device, and mud containing silt and ore pulp containing carnallite raw ore are obtained through centrifugal separation; and the ore pulp is dehalogenated through a dehalogenating device to obtain carnallite raw ore. According to the treatment method of the high-sediment carnallite raw ore, a mixture containing sediment and carnallite raw ore is changed into mixed ore pulp through saturated brine, then the sediment and the carnallite raw ore are separated, and the sediment mixed in the carnallite raw ore is removed in the raw material stage of potash fertilizer production, so that the quality of the raw ore is improved.

Description

technical field [0001] The invention relates to the technical field of raw ore processing, in particular to a method for processing high-silt carnallite raw ore. Background technique [0002] Carnallite raw ore is an important raw material for producing potassium chloride, and its production scale continues to expand. At present, there are mainly two mining methods for carnallite raw ore: dry mining carnallite raw ore and water mining carnallite raw ore. [0003] In the process of dry mining carnallite raw ore, due to factors such as mine pool construction, brine transportation, wind season damming, ore process control, etc., often cause carnallite raw ore to contain a large amount of sediment. In the production process of potassium fertilizer, the sediment is removed by adding flocculants, but with the continuous mining of carnallite raw ore, the amount of sediment contained in it is increasing, and the amount of flocculant is also increasing. The decline in effect will al...
