Problems solved by technology

[0014] However, these collectors all have a large amount of collector use and a complicated drug system (except for the use of common H in the flotation process) 2 SO 4 As a pH regulator, diesel oil and ilmenite activators, etc. need to be added), the cost of the agent is high, and some collectors contain a certain amount of arsenic compounds, which have a great impact on the environment

Abstract

The invention discloses a preparation method for a titanic iron ore floatation collecting agent. The preparation method includes the following steps that vacuum gas oil No.5 dewaxing oil serves as raw oil; a fuming sulphuric acid solution serves as a sulfonating agent, and sulfonating reaction is performed on the raw oil and the sulfonating agent to obtain a sulfonated product; an NaOH solution is used for performing primary saponification on the sulfonated product to obtain sulfonate; the prepared sulfonate, soybean oleic acid and styryl phosphonic acid are compounded to be a mixture; secondary saponification is performed on the mixture after compounding through NaOH solution to obtain the anionic collecting agent. Compared with an existing titanium concentration collecting agent, the prepared titanic iron ore floatation collecting agent is simple in floatation agent rule, small in usage quantity of agents, excellent in floatation index and good in low-temperature floatation performance; the main components of the collecting agent are sulfonic acid and fatty acid, so that the collecting agent is small in influence on the environment and is a green product.

Description

technical field [0001] The invention belongs to the technical field of preparation of ilmenite ore flotation collectors, and in particular relates to a preparation method of ilmenite ore flotation collectors. Background technique [0002] Flotation is the key technology for fine-grained ilmenite to be recycled and utilized. In the nearly sixty years of ilmenite flotation research and application, commonly used ilmenite flotation collectors include: fatty acid collectors, Phosphorus collectors, arsenic collectors, hydroxamic acid collectors and collectors combined with each other. In the ilmenite flotation process, in addition to the collector must be used, activators (such as Pb (NO3) 2), pH regulators (such as H 2 SO 4 ), inhibitors (such as water glass, oxalic acid, sodium hexametaphosphate, carboxymethyl cellulose, etc.), in addition, in order to improve the collection capacity of collectors and the stability of flotation foam in the flotation process, in ilmenite A ce...
