Problems solved by technology

Discontinuous batch processing limits throughput and efficiency, which impacts costs
[0006] There are also continuous methods, such as drum separators, but these have high mechanical investment, high maintenance requirements, and low mass flow rates, making them impractical for many mining methods used in the mining industry

Embodiment Construction

[0016] The two figures will be combined for illustration below.

[0017] figure 1 Each processing step and the corresponding chemical composition are represented by functional boxes, where the bold arrows indicate the sequence of each processing step, and the dotted lines and corresponding arrows represent the material flow of recycled materials.

[0018] The core of method of the present invention and corresponding system is to magnetite (Fe 3 o 4 ) as magnetically activatable adsorbent: powdered magnetite is already hydrophobic, that is to say magnetite is preferably bound to hydrophobic particles in aqueous solution.

[0019] The powdered magnetite to be used is then treated with a surface modifier capable of further strengthening the hydrophobicity of the particle surface. Hydrophobic particles aggregate in aqueous suspensions to minimize their interface with water. If the recyclable ore particles are also selectively hydrophobized, the gangue remains hydrophilic, and ...

Abstract

A method for magnetic ore separation and / or dressing is provided, in which metalliferous recoverable materials are separated from conveyed metalliferous ore rock. The method may include producing a pulp including metalliferous recoverable material, executing a hydrophobizing reaction of recoverable material in the pulp, synthesizing a hydrophobized, magnetizable material in liquid suspension and adding this suspension to the pulp, causing an agglomeration reaction between hydrophobized magnetizable material and hydrophobized recoverable material to form magnetizable agglomerates in the pulp, separating the magnetizable agglomerates from the pulp, mixing separation products containing the agglomerates with a non-polar liquid insoluble in water and decomposing the agglomerates in the non-polar liquid into magnetizable material and recoverable material, separating the magnetizable material from the recoverable material, and removing moisture from the separation portion containing the recoverable material of the second separation stage to synthesize the recoverable material.

Description

technical field [0001] The present invention relates to a continuous magnetic separation and / or ore washing method as described in the preamble of claim 1. According to the invention, during the implementation of the method it should also be possible to wash the substances used before being reintroduced into the treatment process. The invention also relates to a corresponding system for carrying out the method according to claim 11 , which industrially implements the process steps of the method according to the invention by means of corresponding devices / equipment. Background technique [0002] In related mining / washing operations, ore refers to metal-bearing rock from which recyclable material in the form of metal-bearing components needs to be separated. The recyclable substances in copper ore are mainly sulfide-containing copper materials that need to be selected, such as (but not limited to) Cu 2 S. The copper-free rock around the recyclable material particles is call...
