Method for separating talc concentrate from complex talc ore raw materials

Abstract

The invention discloses a method of separating talcum concentrate from a complicated talcum ore raw material. The method comprises the following steps: crushing, impurity removing and screening by taking the complicated talcum ores as a raw material. The method specifically comprises the following steps: 1) crushing and impurity removing: crushing and sorting the complicated talcum ore raw material to remove impurities; 2) ore washing and sorting: feeding the ground talcum material to a washing storage device by means of water, adding a dispersing activator, and washing the ground talcum material with water to remove impurities in a continuous stirring condition to sort a coarse talcum ore material; 3) smashing and grading: pulping the coarse talcum ore material, adding a flocculant to smash the coarse talcum ore material, and grading the coarse talcum ore material gradiently with a grading machine to obtain a talcum ore medium material; 4) screening and grinding: sorting and screeningthe talcum ore medium material again; and 5) magnetic separation: preparing talcum concentrate, and carrying out magnetic separation on rough talcum concentrate to prepare the talcum concentrate. A prepared talcum concentrate product is obvious in economical and technical benefits, small in three waste treatment and high in yield.

Description

[0001] Technical field: [0002] The invention relates to a method for recovering talc concentrate from talc ore raw materials, in particular to a method for separating talc concentrate from complex talc ore raw materials. [0003] Background technique: [0004] Talc is a non-metallic mineral with hydrous magnesium silicate mineral as the main component. The main component of talc is Mg 3 (Si 4 o 10 ) (H 2 O) 2 , The layer-off structure of silicate minerals. It is a high-quality non-metallic mineral resource in my country. At present, the proven reserves of talc mineral resources are nearly 300 million tons. my country's talc mineral resources are mainly distributed in 5 provinces and cities including Liaoning, Shandong, Guangxi, Jiangxi and Qinghai, which account for more than 95% of the national talc mineral resource content. The main component of talc minerals is talc, accompanied by minerals such as magnesite, dolomite, and serpentine. [0005] Talc ore is a very i...

AI Technical Summary

Problems solved by technology

But the processing method of above-mentioned talc mineral, one is that it can only prepare and sort low-quality talc ore;

The above-mentioned simple sorting method can be used to prepare low-quality talc mineral products, and the sorted talc mineral products cannot meet the use of high-end raw materials

And there is the disadvantage of low recovery rate, resulting in a waste of limited resources

[0007] For a complex talc mine, the existing common methods are to use waste rock or simply extract talc, but most of these waste rocks have not been comprehensively utilized except for a few used for filling pits and paving roads.

It has been found that some have accumulated tens of millions of tons. In the above-mentioned talc mines, the industrial grade cannot be reached, and they have been treated as waste mines and waste rocks, which is a waste of resources. It not only affects the mining of other high-quality mineral deposits, but also occupies mountainous land. , and bring serious harm to the surrounding environment, and pose a threat to the lives and property safety of the surrounding people
