Description

Comprehensive disposal system for composite admixture for concrete production by electrolytic manganese dioxide slag

Technical Field

The utility model belongs to the technical field of electrolytic manganese dioxide sediment comprehensive utilization deals with, specifically be the comprehensive processing system of compound admixture for electrolytic manganese dioxide sediment production concrete.

Background

Manganese is an important basic and strategic substance of national economy and is widely applied to high and new technical fields such as steel and non-ferrous metal smelting, electronic batteries, aerospace, national defense industry and the like. Among manganese series products, the electrolytic product yield is very large, second only to manganese series ferroalloys. In manganese series electrolytic products, electrolytic manganese metal and electrolytic manganese dioxide belong to manganese series chemical processing products, the electrolytic manganese metal and the electrolytic manganese dioxide are widely applied and have high yield, but the electrolytic manganese metal and the electrolytic manganese dioxide are applied to different fields. At present, China is the biggest electrolytic manganese dioxide producing country, consuming country and export country in the world as well as the biggest electrolytic manganese dioxide producing country, consuming country and export country in the world. Since 2010, the electrolytic manganese dioxide capacity of China accounts for more than 60% of the global capacity. Although the reserves of manganese ores are rich in China, most of the manganese ore resources with rare ores and slightly high manganese content are used in the metallurgical industry, most of the manganese ore resources can be used for producing electrolytic manganese dioxide and are low-grade manganese carbonate ores, the difficulty of production process (including impurity removal and the like) is increased, and the discharge of waste residues in the production process is relatively increased, so that the comprehensive utilization situation of the waste residues resources in the electrolytic manganese dioxide industry in China is more severe.

The electrolytic manganese dioxide slag and the electrolytic manganese metal slag belong to residues generated in the production process of manganese series electrolytic products, wherein 6-10 tons of waste residues are discharged when 1 ton of electrolytic manganese dioxide or electrolytic manganese metal is produced, the waste residues generated in China every year are as high as 1100 to ten thousand, and the same type of waste residues accumulated in China all the time are added, so that the quantity is extremely remarkable, and the pollution is very serious.

According to the relevant data, the waste slag is buried in a slag disposal site after being mixed with slaked lime and solidified in developed countries such as the United states and Japan, and then, from the aspects of energy saving and environmental protection, the countries such as the United states and Japan shut down part of related enterprises by means of market and administrative means so as to achieve the purpose of radical treatment. Some countries also use tail stores to dispose of such waste residues, but at a very high cost. Most of enterprises for electrolyzing manganese dioxide and manganese metal in China transport waste residues to storage yards for damming and wet-process storage, but many of the waste residues are not subjected to engineering geological exploration during construction, and the problems of seepage prevention and seepage measurement are not considered, so that the waste residues are bound to be continuously polluted by surface or underground seepage after being stored for a long time, and the underground water and soil in the areas are seriously polluted. Therefore, the problem can be solved completely from the source only by fully utilizing the electrolytic manganese dioxide slag as a resource and gradually consuming millions of tons or more of electrolytic manganese dioxide slag which is produced and stockpiled every year.

The production process flow of the electrolytic manganese dioxide can be simply divided into the following five steps:

the first step is as follows: leaching manganese carbonate ore with sulfuric acid to prepare a manganese sulfate solution, removing potassium (the pH value is controlled to be 1.0-2.0), neutralizing, removing iron (the pH value is controlled to be 6.5-7.0), and the like;

the second step is that: filter pressing, solid-liquid separation and waste residue discharge;

the third step: removing heavy metals, molybdenum and the like from a manganese sulfate solution, and purifying other various impurities and suspended matters in the solution to obtain an electrolyte;

the fourth step: electrolyzing (the electrolysis temperature is above 90 ℃), and obtaining manganese dioxide deposit at the anode of the electrolytic cell, namely, electrolyzing a manganese dioxide crude product;

the fifth step: and crushing, neutralizing, rinsing, drying, grinding and homogenizing the crude product to obtain the electrolytic manganese dioxide finished product.

The electrolytic manganese dioxide slag is a high-sulfur-content silicon-aluminum industrial waste, is a blocky substance formed by sticking, gathering and filter-pressing black fine particles, and has the water content of about 28 percent; the waste residue is slightly acidic, and the general PH = 6.18-6.82.

The electrolytic manganese dioxide slag belongs to an inert material at normal temperature, but has a certain degree of potential gelling activity through the drying or heating process. Therefore, from the viewpoint of environmental protection and absorption capacity, the comprehensive utilization of the electrolytic manganese dioxide slag into the category of building materials is undoubtedly an effective way for realizing large-scale resource utilization.

At present, when electrolytic manganese dioxide slag is used for producing building materials, a series of effective treatments of modification and homogenization are mostly not carried out, so that insufficient activity or uneven distribution of harmful substances can be caused in the process of preparing the building materials, the product quality of the building materials can be seriously influenced, and the comprehensive utilization of the electrolytic manganese dioxide slag resource can be hindered.
