Embodiment Construction

[0020] The present invention is described in further detail below in conjunction with embodiment.

[0021] A method for comprehensive recovery of mica-containing sandy kaolin, characterized by:

[0022] A. Crushing, scrubbing, and grading: After crushing the sandy kaolin raw ore to -1mm in two stages, add water and send it into the scrubbing machine for scrubbing, so that the kaolin is fully separated from the quartz sand; the scrubbed slurry enters 325 mesh high-frequency vibration Sieve for screening, -325 mesh slurry is kaolin, +325 mesh material is quartz sand and mica;

[0023] B. Kaolin purification operation: The material under the -325 mesh sieve of the high-frequency vibrating screen enters the first slurry high-gradient magnetic separator for the first stage of magnetic separation operation, the field strength is 1.0 Tesla, and the first medium adopts low-drawing wire mesh Medium, the magnetic matter obtained in the first stage of magnetic separation operation enter...

Abstract

The invention discloses a method for comprehensive recycling of sandy kaolin containing mica. The method specifically comprises the following steps of crushing raw ore of sandy kaolin containing mica, wiping, and grading, wherein the matter under a screen is kaolin, and the matter on the screen is ground by a high alumina ball mill, graded by a spiral grader, and screened by a high-frequency vibration screen, so as to obtain quartz sand and mica, thereby guaranteeing the stripping and granularity control of iron, titanium and other impurities in the quartz sand, and creating conditions for subsequent magnetic sorting process; magnetically sorting the kaolin and the quartz sand at two different strengths, so as to fully ensure the separation and effective removal of magnetic impurities in the kaolin and the quartz sand, effectively recycle the kaolin and the quartz sand, obtain a product with high quality and high added value, and greatly increase the comprehensive recycling rate of resources. The method has the advantage that while the high-quality kaolin and quartz sand are obtained, the valuable mica can be recycled, the discharge of tailings is effectively reduced, the comprehensive utilization rate of resources is increased, and the added value of the product is increased.

Description

technical field [0001] The invention relates to a method for comprehensive recovery of non-metallic mineral resources, in particular to a method for comprehensive recovery of mica-containing sandy kaolin. Background technique [0002] Sandy kaolin is a non-metallic mineral and an important non-metallic mineral material. Pure kaolin is white and delicate, soft and soft, with good physical and chemical properties such as plasticity and fire resistance. It has a wide range of uses, mainly used in papermaking, ceramics and refractory materials, and is the basic material for modern industrial development. The minerals contained in kaolin in nature are mainly divided into clay minerals and non-clay minerals, among which clay minerals mainly include kaolinite minerals and a small amount of montmorillonite, mica and chlorite; non-clay minerals mainly include feldspar, quartz and mica etc. With the rapid development of the national economy, kaolin mineral resources are continuously...
