Problems solved by technology

Otherwise, a satisfactory flocculation effect cannot be achieved when the addition amount is low, or excessive flocculant addition will not only cause waste but also cause the opposite effect, that is, dispersion behavior
Furthermore, despite the high settling velocity of the flocs produced by current commercial flocculants, the structure and properties of such flocs are not conducive to further separation processes such as thickening and filtration
Economically, to overcome the repulsion between solid particles caused by the dispersant, it is necessary to increase the amount of flocculant to achieve satisfactory results, which undoubtedly increases the production cost of the enterprise.

Abstract

The invention discloses a multifunctional ore dressing chemical, and a using technique thereof. The chemical can be widely used for treating various ore resources. A synthesis method of the multifunctional ore dressing chemical comprises the following steps: preparing colloidal solution of an inorganic oxide and a hydroxide; dissolving an organic monomer in the colloidal solution of the inorganicoxide and the hydroxide; adding an initiator into the solution to complete organic synthesis a reaction kettle. The obtained multifunctional ore dressing chemical which has a selective flocculation function is added into the flotation pulp to help ore separation in ore flotation and solid-liquid separation in tailing processing. The using technique comprises: the flotation and tailing processing.The multifunctional ore dressing chemical also can be used in tailing processing alone. The multifunctional ore dressing chemical can improve production efficiency, improve mine environmental protection, greatly improve the economic benefits of the mine, improve the return water recovery effect and reduce mine environment pollution.

Description

Technical field: [0001] The invention relates to the synthesis of mineral dressing agent with multiple functions and its application technology in mineral flotation and tailings treatment, which has the economic and social effects of improving production efficiency and promoting environmental protection. This agent and technology can be widely used in the treatment of different kinds of mineral resources, such as ferrous metals, non-ferrous metals, coal and non-metallic minerals. Background technique: [0002] my country's mineral resources are very rich in types and reserves, but there are also characteristics such as low grade of raw ore, complex distribution of minerals and difficult processing. Therefore, the mined ore needs to be processed in a beneficiation plant before entering the smelter to separate and enrich different minerals. At present, the most widely used method is froth flotation, and almost all ores can be separated by this method. select. The flotation m...
