Abstract

The invention relates the mineral separation process for low-grade collophane. The method comprises the following steps: carrying out dense-media dressing ore for low-grade collophane, getting the finished ore, then carrying out double reverse flotation, removing magnesium and silicon, and getting the phosphor concentrate. The method transforms the low-grade cellophane to high-grade concentrate, and recovery ratio is more than 80%, solving the problem that the low-grade cellophane is hard to utilize in industry.

Description

The beneficiation method of middle low grade collophanite
Technical field
The present invention relates to a kind of flotation of phosphate rock method, particularly a kind of in the beneficiation method of low-grade silicon calcium quality ore.
Background technology
China's phosphate rock resource is abundant, and particularly silicon calcium quality ore is the important raw and processed materials of producing the phosphate fertilizer product.Silicon calcium quality ore is commonly called as " collophane ", belongs to the appositional pattern phosphorite, and ore mineral is a carbonate fluorapatite, and gangue mineral is mainly dolomite, clay mineral, quartz, potassic feldspar etc.At present, heavymedia separation, direct flotation, reverse flotation, positive reverse flotation, two reverse floatation process are mainly adopted in the collophane ore dressing both at home and abroad, in for low-grade collophane, single heavymedia separation is difficult to obtain high-grade qualified concentrate containing; When direct flotation reaches-200 orders and accounts for 90% left and right sides at grinding particle size, just can obtain satisfied floatation indicators, and the rate of recovery is too low; The same existence of positive reverse flotation requires mog too thin, and how industrial production realizes recycling water utilization, how to avoid problems such as zwitterion collecting agent interaction; Though two reverse flotations can obtain qualified concentrate containing, the rate of recovery is too low, and beneficiation cost is too high.
Summary of the invention
The purpose of this invention is to provide a kind of rate of recovery height, beneficiation cost is low, can access qualified concentrate product, the beneficiation method of the middle low grade collophanite of low taste collophane resource in making full use of.
The object of the present invention is achieved like this: the beneficiation method of low grade collophanite in a kind of, (1), carries the smart tail of throwing with heavymedia separation technology: crushing raw ore is become below the 20mm, raw ore after the fragmentation adds the heavy weight additive magnetic iron ore and enters the heavy medium cyclone sorting, and dense medium separation density is 2.0g/cm 3~3.0g/cm 3, obtaining concentrate and tailings, concentrate obtains heavymedia separation concentrate product through a de-mediated of sieve bend and secondary de-mediated.(2), silicon falls in two reverse flotation de-maggings: the concentrate that heavymedia separation is obtained carries out ore grinding, reaching fineness-200 order during ore grinding is 70%~80%, through cyclone classification, the classification effluent concentration is 32%~38%, the overflow ore pulp enters reverse flotation, at first is the demagging reverse flotation, adopts one roughing, once purging selection, the closed circuit flow process that chats returns, floatation process carries out at normal temperatures, and mash acid alkalinity remains pH=4~6, demagging is roughly selected concentrate and is fallen the silicon reverse flotation again, adopt one roughing, the closed circuit flow process that once purging selection, chats return, floatation process still carries out at normal temperatures, obtains qualified phosphorus mineral product after finishing above-mentioned technical process.
The beneficiation method of low grade collophanite in provided by the present invention, grade by low-grade collophane among the heavymedia separation general raises, and throw and remove a part of gangue mineral, reduced the ore grinding load and the dosing of two anti-floating technologies, greatly reduce the beneficiation cost of two reverse floatation process; Adopt heavymedia separation and two reverse flotation process integration, beneficiation cost is low, can obtain satisfied floatation indicators, produces qualified concentrate containing: P 2O 5Grade is more than 31.5%, and MgO content is below 1%, concentrate P 2O 5The rate of recovery is more than 80%, and is very big for the real value of large-scale industrial production.
The specific embodiment
Embodiments of the invention: use raw ore P 2O 523.63%, the low grade collophanite of MgO 1.83%, concrete technology is as follows:
(1), heavymedia separation: adopt carse, medium and small three section one closed circuit crushing system, with crushing raw ore one-tenth-15mm, be transported to the raw ore storage silo by belt, enter the cyclone that heavily is situated between through adhesive tape conveyor, heavily be situated between and add the heavy weight additive magnetic iron ore in the cyclone, consumption is 4kg/t, and control dense medium separation density is 2.0g/cm 3~3.0g/cm 3, behind dual medium cyclone dressing, obtain concentrate and tailings, after a de-mediated of sieve bend and the de-mediated of sculping screen secondary, become the final concentrate product, concentrate P 2O 5Grade 28.92%, the rate of recovery are 90.90%.
(2), the silicon ore-dressing technique falls in two reverse flotation de-maggings: the concentrate that heavymedia separation obtains is through the ball mill ore grinding, ore milling concentration is about 60%, it is about 70% that mog reaches-200 orders, through cyclone classification, the classification effluent concentration is 35%, the underflow ore pulp enters ball mill and regrinds, and the classifier overflow product delivers to 1 by sand pump #Tank diameter is sized mixing and is added phosphate adjustment, and mash acid alkalinity remains about pH=5, and the ore pulp gravity flow enters 2 #Tank diameter adds collecting agent PA-56, and the material gravity flow after sizing mixing feeds the magnesium that selects of XCF-1 type five trough floatation machines composition and roughly selects operation.Magnesium is roughly selected froth pulp and is added the phosphoric acid back of sizing mixing and be elected to be and already select again from flowing to the magnesium of being made up of two trough floatation machines, and magnesium selects froth pulp-mine tailing 1 to deliver to tailing pit by sand pump again, and magnesium is chosen the ore deposit to return again to select magnesium to roughly select operation and formed closed circuit flotation.Select magnesium to roughly select the underflow product and send into 3 by sand pump #After tank diameter adding adjustment agent G-02 sized mixing, the ore pulp gravity flow entered 4 #Tank diameter adds the TA-04 collecting agent, the silicon that enters four trough floatation machines composition after sizing mixing is roughly selected operation, silicon is roughly selected froth pulp and is selected from flowing to two trough floatation machines again, silicon is chosen the ore deposit to return again to select silicon to roughly select operation and is formed closed circuit flotation, silicon selects froth pulp-mine tailing 2 to deliver to tailing pit by sand pump again, mix by same sand pump with mine tailing 1 and to send into tailing pit, select the silicon concentrate to be sent to the concentrate pond, obtain final concentrate P by sand pump 2O 5Grade is 31.85%, MgO grade 0.76%, and the rate of recovery is 85.5%, obtains producing the acceptable material of phosphorus ammonium.Collecting agent PA-56 adjusts agent G-02, and collecting agent TA-04 adopts Lianyungang Design and Research Institute's product.
