Abstract

Novel flotation collecting-foaming agent belongs to the ore dressing floating agent, is applicable to floatation process such as coal, graphite and molybdenite; The auxiliary flotation agent that also can be used as apatite and tungsten ore etc.The feature of this flotation agent is to utilize the byproduct and the process product processed thereof of producing the cyclohexanol and cyclohexanone mixture, being the byproduct and the process product processed thereof of producing hexanedioic acid, is that chemical fibre is produced cyclohexanol and the byproduct of cyclohexanone mixture and the Compound Machining product of other fraction of oil or product.Compare with conventional oils medicament, this flotation agent has energy-conservation and flotation efficiency height, advantage such as cheap.

Description

Novel collecting-the foaming agent of floatation process

The present invention relates to the floating agent of ore-dressing technique.

In the floatation process of metalliferous minerals such as nonmetallic minerals such as coal, graphite and tungsten ore, use the fractionation product (as kerosene and light diesel fuel) of oil to make collecting agent always, but, directly use because of containing the flotation inert component in the petroleum fractionating product, ton coal (ore deposit) oil consumption height, the waste resource; Or with various bipolar moleculars (as alcohols, ether alcohol and ketols molecule, do foaming agent and promoter, though effective, processing technology complexity, price height.So, be necessary to develop a kind of usefulness height, cheap floating agent.

Purpose of the present invention is to utilize industrial leftover bits and pieces, and a kind of cheap efficiently flotation agent is provided.

The primary raw material that the present invention is used, be in the cheap byproduct in chemical fibre factory to the effective component of flotation:

(category-A) produces the byproduct (code name 83 or X oil) of cyclohexanol and cyclohexanone, and it basic composition is complicated mixture such as alcohol ketone, monoacid, binary acid, cyclohexane, the tert-butyl alcohol and neutrals;

(category-B) produces the byproduct of adipic acid, and its Main Ingredients and Appearance is complex mixtures such as cyclopentanone and light component;

The batching that the present invention is used is the fractionation product of oil:

(C class) C ₁₀Aromatic hydrocarbons, C ₉Aromatic hydrocarbons, a line aromatic hydrocarbons and pyrolysis fuel oil aromatic hydrocarbons: 110 ℃ of initial boiling points, do 210 ℃ C ₁₀Aromatic hydrocarbons; 190 ℃ of initial boiling points, do 250 ℃ aromatic hydrocarbons; 90～200 ℃ of initial boiling points, do 250～290 ℃ pyrolysis fuel oil class; 140 ℃ of initial boiling points, do 240 ℃ C ₉Aromatic hydrocarbons.

(D class) C ₇～C ₁₅The alkane of alkane or 140～300 ℃ (positive structure and isomery), unsaturated hydrocarbons, cycloalkane or non-polar hydrocarbon oil such as kerosene, light diesel fuel.

(category-A) and (category-B) processed with known method of purification.Primary raw material and batching, carry out Compound Machining in following ratio:

XA: YC; XB: YC; UA: VC: WD; UB: VC: WD, in the formula, X, Y, U, V, W are corresponding coefficient, X=0.3～2.0; Y=2～1; U=0.3～2.5; V=2.0～0.5; W=0.5～5.0.

Compared with prior art, the present invention has following good effect:

1. no matter use separately or the process Compound Machining, this flotation agent all has the low advantage of cost;

2. compare with conventional hydrocarbon-type oil collecting agent, this flotation agent consumption is lower, saves more than 1/3 approximately;

3. this flotation agent adopts the byproduct of long line refinery products and chemical fibre factory, has realized fully utilizing and making rational use of resources, and has saved the short-term refinery products and the higher foaming agent of price of respective numbers.

4. this flotation agent has the dual-use function of collecting agent and foaming agent concurrently, not only saves consumption, and cheap, for coal preparation plant and medicament manufactory have brought obvious economic benefit.

Enforcement of the present invention is should get different preparation programs at different atures of coal.For example, will produce cyclohexanol and cyclohexanone byproduct, after known method of purification processing, with C ₁₀Aromatic hydrocarbons and kerosene can make a kind of product of M series flotation agent by 0.5: 1: 1 Compound Machining, and the comparable conventional dose system of effect is saved more than 30%.
