Abstract
The present invention discloses a fluorite calcium-removing cencentrating process. It is formed from once rough-separation and multiple conuentrating operation, and is characterized by that is uses oleic acid or its substitute as collecting agnet to make rough-separation, and uses the mixture of sulfuric acid and acid water glass as inhibitor of calcium-containing mineral material, the ratio of sulfuric acid and acid water glass is 1:0.5-1:2, and its combined dosage is 0.5-1.5 kg/t (green ore). Said invented process is simple in technological process, high in calcium-removing efficiency and low in cost, can separate out special-grade fluorite concentrate with lowest calcium carbonate content from high-calcium fluorite ore.
Description
The present invention relates to the ore-dressing technique of a kind of fluorite ore deposit deliming, be particularly useful for from high-calcium type fluorite ore deposit, selecting superfine fluorite concentrate.
At present, the beneficiation method that is used for Cann calcium-removing both at home and abroad is mainly floatation, enlarges the surface characteristic difference of fluorite and calcium mineral by selecting suitable floating agent for use, thereby reaches the purpose of separation.Introduced the method for fluorite and calcium mineral FLOTATION SEPARATION in " fluorite separates with Calcite by Flotation " literary composition that " metal mine " 1996 the 12nd periodicals are stepped on, floating agent comprises collecting agent and adjusts agent.Collecting agent commonly used is mainly the substitute of oleic acid and oleic acid; The kind of adjusting agent is a lot, as soda, lime, phosphate, waterglass, tannin class and lignosulphonates etc.This article is thought, reaches the requirement to PH values according to ore character, used collecting agent kind, and particularly inhibitor is extremely important to select suitable adjustment agent for use, obtains the key of high-quality concentrate often.But when the raw ore calcium carbonate content is too high, adopt the inhibitor of above-mentioned recommendation such as waterglass, phosphate, lime etc., then be difficult to obtain promising result, so that some factories and mines when running into this type of ore, is stored up because of can't only handling.45 pages of " metal mining industry digest " the 10th phases in 1986, introduced a kind of chemical beneficiation process of low grade fluorite concentrate, adopt method of pickling to remove calcium carbonate in the fluorite concentrate, but this method cost height, and complex process, be difficult to implement in existing factory.
The object of the invention is exactly the problems referred to above that exist in the existing Cann calcium-removing beneficiation method, and provides a kind of technology Cann calcium-removing ore-dressing technology simple, with low cost, and it can make in the fluorite concentrate content of calcium reduce to the requirement that meets superfine concentrate standard.
For achieving the above object, Cann calcium-removing ore-dressing technology of the present invention by the following technical solutions:
Cann calcium-removing ore-dressing technology of the present invention is by one roughing, repeatedly selected operation is formed, roughly select as collecting agent with oleic acid or its substitute, suppress calcium mineral with sulfuric acid and acidic water glass, the ratio of sulfuric acid and acidic water glass is 1: 0.5～1: 2, and combined amount is 0.5～1.5kg/t
Raw ore
The ratio of above-mentioned sulfuric acid and acidic water glass be 1: 1～1: 1.5 for best.
Described acidic water glass is that sulfuric acid and waterglass mix with 1: 0.6～1.5 ratios under 2%～10% concentration, to be mixed into the best with 1: 1 proportioning under 4～6% concentration.Described sulfuric acid changes because of the different of raw ore calcium content with the ratio and the combined amount of acidic water glass, and when the raw ore calcium carbonate content was high, sulfuric acid and acidic water glass ratio were got low, and the sulfuric acid consumption is added, otherwise then adds less.
For the uneven ore of disseminated grain size, can when corase grind, obtain a part of concentrate, abandon mine tailing, chats is concentrated regrinding and reconcentration then, to obtain another part concentrate.This throws tail with the corase grind of routine, coarse concentrate regrinding selects and compares, and has reduced the ore deposit amount of regrinding, and because of the overground loss that causes, has got rid of the difficulty that causes because of rough concentrate foam transport point when having avoided that the fluorite mineral of monomer dissociation have been regrinded.
To containing silicium calcareous high fluorite ore deposit, roughly select and can in alkaline medium, carry out, use waterglass to be inhibitor, in rougher tailings, to abandon the siliceous mineral more than 90%, in selected operation, add sulfuric acid and acidic water glass then, can strengthen the deliming effect like this, reduce the deliming dosing.
Cann calcium-removing ore-dressing technology provided by the invention is united the inhibitor of use as calcium mineral with sulfuric acid and acidic water glass, sulfuric acid can make calcite mineral surface produce selective dissolution, and lose collecting agent rely absorption the active region, the inhibitory action of acidic water glass is strengthened, thereby obtained high-quality concentrate.Have the ca efficiency height of removing, technology advantage simple, with low cost.
For further describing the present invention, enumerated some examples below, wherein embodiment 1 adopts technical scheme provided by the invention to sort the detailed result of the test in fluorite ore deposit, Zhejiang, and embodiment 2～6 is a contrast test.
Embodiment 1: the fluorite raw ore picks up from fluorite ore deposit, Zhejiang, and this ore deposit belongs to high silicon high-calcium type, and disseminated grain size is inhomogeneous, its essential mineral consists of: fluorite, quartz, calcite, calcedony and opal etc., in addition, a spot of pyrite, apatite and secondary kaolin etc. are arranged still, raw ore contains CaF
239.15%, SiO
248.50%, CaCO
35.98%.Raw ore is roughly ground the millimeter to 55%-0.076, under alkaline medium, add waterglass and oleic acid, remove the SiO more than 90% when roughly selecting
2, froth pulp adds sulfuric acid and acidic water glass after primary cleaning, and froth pulp obtains the part fluorite concentrate through four times after selected after twice deliming; The product merging is regrinded to the 90%-0.076 millimeter in four the selected grooves in back, obtains another part fluorite concentrate after thick three essences, and two parts fluorite concentrate is merged into final concentrate, and experimental condition sees Table 1, and result of the test sees Table 2.
