Looking for technologies for refining processing of Kaolin clay

Using nanotechnology to resolve refining processing of Kaolin clay

Overview

We are looking for technologies that can solve the following problems:

1. Separation and purification of low-grade Kaolin clay

Make effective separation and purification of low-grade Kaolin clay through the combined flowsheet of gravity treatment, floatation, magnetic separation and chemical treatment taking into consideration the differences of density, surface property and electromagnetic properties between the Kaolin clay and the impurities of the clay.

2. Refining mineral processing technologies:

Ultra-refinement technology, classification technology and bleaching process of Kaolin clay using chemical methods and physical methods in the removal of iron, titanium and sulfur.

3.Surface modification of Kaolin clay.

Searching for technologies for Kaolin production for different uses when treated with different surface-treating agents and analyzing production properties such as surface structure, surface energy, surface area, surface potential, stability suspension, particle size composition, viscosity, rheological behavior and microstructure. Study the modification mechanism of different surface-treating agents and carry out the best one and the best combination.

Expected targets and technical milestones:

1. Improve reparability of low-grade Kaolin clay and make the most of current mineral resources.

2. Impove technology by control ore pulps concentration, particle distribution, Fe2+ concentration, PH value, growth circle of TF bacterium and oxidation time.

3. Solve the problem of single-product, unsteadiness of quality, high-energy-consumption and low production capacity of modified production, at the same time increase the product performance, reduce energy consumption and extend application field to fill the market demand.

4. Realize online examine during production process of slurry concentration, viscosity and particle size, meanwhile realizing automatic control of slurry concentration, stir speed, stay time of material, slurry pressure, filter-pressing period, dosage of  surface-treating agents and the reaction time.
