Problems solved by technology

However, because the carbon in stone coal is hydrophobic and easy to float, the loss of carbon in the flotation process is serious, and at the same time, some vanadium minerals are also carried out, which reduces the economic benefits of stone coal resource utilization.
Ammonium salt vanadium separation, although this method can enrich the vanadium resources in stone coal and reduce the economic cost of vanadium extraction, but because the utilization of carbon resources in stone coal is not considered, it is difficult to regenerate the carbon in stone coal. Therefore, the comprehensive utilization value of stone coal resources has not been improved

Abstract

The invention relates to a composite beneficiation reagent for extracting vanadium from stone coal. The composite beneficiation reagent for extracting the vanadium from the stone coal is characterized in that the composite beneficiation reagent is composed of a component A, a component B, a component C, a component D and water, the component A is kerosene and/ or diesel oil, the component B is quaternary ammonium salt class matter and/ or aliphatic amine hydrochloride class matter, the component C is any one or more of alcohol ranging from C4 to C8, 4-methyl-cyclohexyl-methanol, MIBC, terpenic oil, methyl triisopropoxy silane, and the component D is any one or more of alkyl-sulfonate ranging from C8 to C12, OP-10 and Tween-60. The composite beneficiation reagent for extracting the vanadium from the stone coal is prepared by a plurality of components according to a certain proportion and a rule, combination of the components of the reagent can be adjusted according to different mineral properties so that a series of flotation reagents can be prepared, and thebest use effect is achieved.

Description

technical field [0001] A compound beneficiation agent for vanadium extraction from stone coal. It relates to a composite mineral dressing agent for extracting vanadium from stone coal. Background technique [0002] Stone coal is a polymetallic paragenetic ore with low carbon content, low calorific value and low grade. The calorific value of stone coal is not high, generally around 800 kcal / kg, and it is a low calorific value fuel. More than 60 kinds of associated elements have been found in my country's stone coal resources, among which vanadium is the main one that can form industrial deposits, followed by molybdenum, uranium, phosphorus, silver and so on. [0003] my country is rich in stone coal resources. How to study and extract vanadium and other associated elements while making full use of the low calorific value energy of stone coal can not only improve the utilization value of stone coal, but also provide more urgently needed metal materials for my country's natio...
