Production process of paste attapulgite clay

Abstract

The invention provides a process of preparing paste formed attapulgite clay. The key points of the technical proposal include: the process of preparing paste formed attapulgite clay comprises the steps of pulping, sodium treatment, acidizing treatment, water washing and impurity screening out, and the mud obtained is subjected to precipitation to obtain the paste formed attapulgite clay. The attapulgite ore mud is subjected to the steps of sodium treatment, acidizing treatment, water washing and impurity screening out, and become natural gel with good thixotropy and stickiness, and the pH value is neutral. The attapulgite clay obtained by the preparation process of the invention has viscosity, expansion capacity, colloid value, whiteness degree, specific surface area, adsorbability and dirt removing power greatly improved, and the invention is suitably applied to the production of the paste formed attapulgite clay.

Description

Technical field: [0001] The invention relates to a production process of clay, in particular to a production process of paste-like attapulgite clay. Background technique: [0002] Attapulgite ore after wet beneficiation, using attapulgite ore pulping production process, can effectively improve the utilization rate of attapulgite ore and the attapulgite content of ore, and can be further processed into high-grade products, but it should be applied in high quality requirements Further modifications are required in the products.
