en.Wedoany.com Reported - The invention patent for "a mineral desliming and dispersing device and its application," developed by the Guangxi Geological and Mineral Testing Research Center in China, was recently publicly authorized by the National Intellectual Property Administration. This desliming and dispersing device provides a solution to the long-standing problems in the beneficiation pretreatment of clay-containing minerals and claystone ores, namely "high noise from large particles, incomplete washing of small particles, and inability to break up micro-fine flocs." The bottleneck of "incomplete washing and inability to break up" in traditional processes has long troubled the industry. This desliming and dispersing device directly addresses these pain points through structural innovation.

In traditional beneficiation processes, the desliming and dispersion pretreatment of clay-containing minerals and claystone ores has always been an industry difficulty. Factories commonly use manual scrubbing or equipment like drum washers and spiral washers for multi-stage ore washing and desliming, which is not only inefficient but also yields poor cleaning results for minerals with irregular surfaces, easily leaving impurities that affect subsequent separation accuracy. For the purification and modification of claystone ores such as kaolinite and bentonite, existing mixing equipment often suffers from synchronous movement of the slurry and impeller and insufficient shear force, making micro-fine flocs difficult to break up and preventing improvements in processing efficiency. The desliming and dispersing device launched by the Guangxi Geological and Mineral Testing Research Center is specifically designed to address these two types of problems.

This invention patent breaks away from the old approach of traditional equipment relying on drum self-friction or impeller synchronous stirring. Through optimized design, the desliming and dispersing device achieves efficient desliming and powerful dispersion for ores of different particle sizes, effectively overcoming the process bottlenecks of "incomplete washing and inability to break up." The project leader introduced: "This technology can be widely applied to the desliming pretreatment of clay-containing minerals such as bauxite, placer gold, and manganese ore, as well as the mixing and dispersion stages for claystone ores like kaolinite and bentonite." The core breakthrough of this desliming and dispersing device lies in simultaneously solving problems on three levels: high noise from large particles, residue from small particles, and the difficulty of breaking up micro-fine flocs.

Currently, this desliming and dispersing device has entered the industrial application verification stage. After widespread promotion and application, it is expected to reduce beneficiation production costs, improve comprehensive resource utilization, decrease reagent consumption, enhance the working environment, and propel the mineral processing industry towards the goals of green, efficient, and low-carbon development.
