Active stimulating grinding aid for ferronickel slag and preparation method thereof

Abstract

The invention discloses an active excitatory grinding aid for ferronickel slag and a preparation method for the active excitatory grinding aid. The grinding aid is composed of polymeric glycol, cocoanut fatty acid diethanolamide, sodium pyrophosphate, ethyl acetate, an excitant and water, wherein the excitant is composed of calcined alunite, water glass and sodium abietate. The additive amount of the grinding aid in the ferronickel slag is 0.02-0.10% by mass of the ferronickel slag. The active excitatory grinding aid disclosed by the invention is sufficient in raw materials, simple to process and prepare, low in doping amount, stable in performance and high in cost performance. As the ferronickel slag which is ground is added, the problem that the ferronickel slag is poor in grindability can be solved. Under the condition that the grinding time is equal, the specific surface area of the ferronickel slag micropowder can be improved by 4.5-9%, the mill output is increased by over 15%, the energy consumption is remarkably reduced, and moreover, the active index of the ferronickel slag can be further improved by 10-35%.

Description

technical field [0001] The invention relates to the field of resource utilization of industrial waste slag, in particular to an active stimulating grinding aid for ferronickel slag and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economic construction, a large amount of non-ferrous metallurgical waste residues have been produced in the process of industrial production. Ferronickel smelting waste slag from lateritic nickel ore (referred to as ferronickel slag) is a kind of granulated slag formed by refining nickel metal or the waste discharged during the smelting process of nickel-iron alloy, which is quenched in cold water. According to statistics, in 2013, my country's annual output of ferronickel reached 710,000 tons, accompanied by more than 45 million tons of ferronickel slag. By 2015, it is estimated that the total discharge of ferronickel slag will be close to 100 million tons, exceeding the to...
