Description
Technical Field
The invention belongs to the technical field of comprehensive utilization of copper tailings, and particularly relates to a copper tailing modifier as well as a preparation method and application thereof.
Background
As is well known, scientific and reasonable development and utilization of mineral resources are important basic stones for human survival and social development, and the production and manufacture of most industrial products, consumer products, energy sources and raw materials depend on the development and utilization of mineral resources. Copper is widely applied to industries such as electricity, light industry, mechanical manufacturing, building industry, national defense industry and the like as a mineral resource with huge demand, wherein the usage amount of copper in China is second to aluminum in consumption of non-ferrous metal materials. However, copper ore mined from mines must go through a series of mineral separation processes before being refined into high-purity refined copper and copper products, wherein most gangue minerals in the copper ore become copper tailings after being crushed and refined. The data show that about 400 tons of copper tailings are generated for every 1 ton of refined copper produced under the current process technology. According to the statistical analysis of China's national resource economic research institute, the total emission amount of the copper tailings in China reaches 24 hundred million tons between 1949 and 2007, and the emission amount is continuously increased. The annual output of the copper tailings in China in 2013 reaches 3.19 hundred million tons, and the quantity is incredible.
A huge amount of copper tailings serving as solid waste are generally directly discharged into a tailings pond in a slurry form for stockpiling in China, few copper tailings serving as filling materials are backfilled into an excavated mine, and the comprehensive utilization level of the copper tailings is low. The stockpiling of a large amount of copper tailings can cause various disadvantages: (1) occupies a large amount of agriculture and forestry land, and causes land resource imbalance. Meanwhile, the tailings pond often has collapse and leakage accidents, or the excessive drainage and the like can also damage a large amount of land. (2) Increasing the operating cost of the enterprise. The tailings treatment facility is a building with higher requirement on neutralization performance of mineral separation enterprises, and the capital investment of the tailings treatment facility is up to 5-40%. And the routine maintenance and operation management of the tailings pond are also considerable expenses. (3) And the environment is polluted. The tailings generally contain a lot of heavy metal ions, and various chemical agents can be introduced in the processing process of copper ores, so that the tailings can seriously pollute the ecological environment of nearby areas once the tailings are poorly treated and enter the surrounding natural world. In conclusion, the accumulation of copper tailings brings about a nuisance and no advantage.
The mineral composition of the copper tailings is mainly silicate minerals such as quartz, mica, sodium/potassium feldspar and the like or carbonate minerals such as calcite and the like, and the copper tailings have obvious resource attributes. Due to the limitations of a series of factors such as the technical level, equipment performance, economic conditions, manual operation of actual production and the like of the past and capital industry, the copper tailings cannot be well utilized.
