Abstract

The invention relates to a method for making a ceramic tile material by modifying gold ore tailings by utilizing weakly acidic clays, and belongs to the technical fields of tailing recycling and materials. The method comprises the following steps: standing the weakly acidic clays and a water solid-liquid mixing system at normal temperature for certain time to form an initial solution of modified tailings; then allocating the gold ore tailings into an initial solution system for modification; maintaining a mixed system formed by obtained modified gold tailings and the modified initial solution, and carrying out sufficient reaction on the weakly acidic modified initial solution and the modified gold tailings to form a blank body for preparing a ceramic tile; finally preparing the ceramic tile material by virtue of extrusion and electrical kiln burning. The ceramic tile material can not only be used as an unglazed ceramic tile material, but also be used as a glazed ceramic tile material after the surface is glazed. The invention provides a new technical method for realizing the high-efficiency decrement utilization of the gold tailings and seeking a low-cost novel resource for the ceramic tile material.

Description

technical field [0001] The invention relates to a method for making pottery bricks by using weakly acidic clay modified gold ore tailings, and belongs to the technical field of tailings resource utilization technology and materials. Background technique [0002] The relative content of gold minerals in gold deposits is very small, so that the amount of tailings produced during the mining process is particularly large, which causes great harm to the ecological environment and people's lives. Tailings are also a special mineral resource, but its resource utilization, reduction and efficient utilization are still a challenge. [0003] Clay is an inexpensive material that is widely distributed. Ceramic brick materials are widely used in daily life, urban construction, etc., and the amount of raw materials used and the amount of waste in the production process are large. If the ceramic brick material is produced by the method provided by the invention, on the one hand, the prod...
