1. A lot of work has been done in the comprehensive utilization of white mud at home and abroad, mainly including the production of ordinary portland cement, alkali slag bricks and plastering mortar, the use of white mud for flue gas desulfurization, and the production of calcium-magnesium fertilizer or soil improver, rubber material, alkali slag and filler.
2. In August 2005, Qingdao Alkali Industry Co., Ltd. extracted a sterilization and yield-increasing health care product from white mud, which was used in fish and shrimp ponds. This product has been tested many times and the effect is obvious. At present, this technology has been officially put into use, and it can consume 20,000 tons of white mud every year. Although the treatment capacity of white mud is limited, it significantly accelerates the process of white mud treatment and is a new breakthrough in comprehensive utilization of white mud.
Extended data:
Genesis of deposit:
1. Kaolin is a common and very important clay mineral in nature. It is formed by weathering feldspar or other silicate minerals in igneous rocks and metamorphic rocks in acidic media lacking alkali metals and alkaline earth metals.
Soil classification:
1. The minerals contained in kaolin in nature are mainly divided into clay minerals and non-clay minerals. Clay minerals mainly include kaolinite minerals and a small amount of montmorillonite, mica and chlorite.
2. Non-clay minerals mainly include the hydrates of feldspar, feldspar and feldspar, iron minerals such as hematite, siderite and limonite, titanium minerals such as rutile and organic substances such as plant fibers. The properties of kaolin are mainly determined by clay minerals.
