A kind of spodumene high-efficiency combined collector and its preparation method and application

Abstract

The invention provides a spodumene high-efficiency combined collector, which comprises: 50-60 parts of oxidized paraffin soap 733 powder, 5-15 parts of sodium naphthenate, 10-15 parts of fat Sodium alcohol polyoxyethylene ether carboxylate, 10-20 parts of quaternary ammonium salt. The present invention also provides a method for preparing the above-mentioned collector, the method comprising the steps: 1) in parts by weight, take 50-60 parts of oxidized paraffin wax soap 733 powder, 5-15 parts of sodium naphthenate, and 10-15 parts of fat Alcohol polyoxyethylene ether sodium carboxylate, 10-20 parts of quaternary ammonium salt, mixed; 2) Add water whose weight is 4-19 times the total weight of the obtained product in step 1), fully stir in a water bath, and the product is obtained. The invention also discloses the application of the above-mentioned collector in flotation separation of spodumene. The collector of the present invention has wide sources of raw materials, low price, strong collecting ability, strong resistance to hard water, strong mudification resistance, good selectivity, and high concentrate yield; the collector of the present invention is simple to prepare, has a wide range of applications, and can Efficient and selective flotation of spodumene in mining environment and in a wide range of pH.

Description

technical field [0001] The invention belongs to the field of flotation collectors, and in particular relates to a spodumene high-efficiency combined collector and its preparation method and application. Background technique [0002] Spodumene, as the main raw material of lithium chemical products, is widely used in lithium chemical industry, glass, and ceramic industries, and enjoys the reputation of "industrial monosodium glutamate". Lithium is an important energy metal. A quarter of lithium is used to store energy. It is also used in thermonuclear reactions such as atomic energy and aerospace. It is called "the energy metal that promotes the progress of the world" and "the energy life metal". , "New energy in the 21st century", has extremely high strategic value and plays an important role in the development and progress of society. At present, the consumption demand of lithium metal in my country is growing rapidly at a rate of 25% per year, and lithium ore is facing a g...

Problems solved by technology

These characteristics make it difficult to develop spodumene mines in my country, the processing cost has been high, the comprehensive economic benefits are poor, and the resource advantages have not yet been transformed into economic advantages.

[0004] In the practice of spodumene separation in my country, there are mainly the following problems: (1) Most of the collectors used are fatty acids and their soap collectors, such as single oxidized paraffin wax soap and naphthenic acid commonly used in industrial practice Soaps have the disadvantages of poor water solubility, low temperature resistance, large dosage, and poor selectivity; (2) complex preparation and high cost, such as CN102921559A, which not only uses expensive chelating collectors but also has a cumbersome preparation process; (3) implementation conditions Harsh, the amount of collector used is large and the pH range is narrow, which makes the amount of reagent used in production large and increases the difficulty of process automation control
