Abstract
Hydroximic acid collecting agent, sodium silicate and general foaming agent (such as ketol oil) are adopted to separate high-grade bastnaesite and monazite mixed concentrate from the low-grade bastnaesite and monazite mixed raw material of Bayan Obo, and then phthalic anhydride hydrolysis or phthalic acid hemisaponificate and aluminum salt are adopted to separate bastnaesite and monazite, so that bastnaesite (REO 69.68%) and monazite concentrate (REO 66.03%) with the total rare earth mineral content of more than 95% of target rare earth mineral are respectively obtained, the process flow is simple, and the separation efficiency is high. The content of harmful elements in the tailing water is lower than the sewage discharge standard.
Description
The invention belongs to mineral engineering RE mineral floating separating technology.
Bastnaesite separates with monazite, adopts floatation usually.The key of floatation is the selection and the PH values of floating agent.It is collecting agent with the sulfosuccinate that Japan equals 1984 to the well taste, is inhibitor with sodium metasilicate, aluminium chloride, with 5
#Pine tar is a foaming agent, in slurry pH 2.89～3.88,53～59 ℃ of slurry temperatures, under the condition of pulp density 7.5%, be raw material, carried out sorting bastnaesite small-scale test with baiyuneboite low-grade [Ce+La+Pr+Nd 9.21%] ore, acquisition contains Ce+La+Pr+Nd59.76%, the bastnaesite concentrate of yield 18.68%, but do not carry out continuous extension trial and do not obtain monazite concentrate No. the 3rd, Japan's " flotation " the 31st volume [220～221 pages, 1984].
The objective of the invention is to solve separating of bastnaesite and monazite, it is simple to seek a kind of technology, and cost is low, and efficiency of separation height is suitable for the floatation process of suitability for industrialized production.
Main points of the present invention are: (1) adopts hydroximic acid collecting agent, sodium metasilicate and general foaming agent (as 210 keto-alcohol wet goods), with mineral such as low-grade bastnaesite and monazites is raw material, under flotation pulp pH value 8.5～9.5 and normal temperature condition, carry out separating of rare-earth mineral and impure mineral, obtain high-grade bastnaesite and monazite (3: 2) bulk concentrate.
(2) saponified with phthalic anhydride heating hydrolysis or phthalic acid half, saponification pH value 3.5～5, as the bastnaesite collecting agent, with aluminium salt (alum, aluminum sulfate or aluminium chloride) as monazite inhibitor, under flotation medium pH value 4～5.5 and normal temperature condition, be that raw material carries out separating of bastnaesite and monazite will put 1 high-grade RE concentrate.
According to main points (1), mainly be to utilize sodium metasilicate to suppress impure mineral, but excessive rare-earth mineral also had inhibitory action, flotation temperature is too high, and the apatite float-amount increases, and influences concentrate grade; Flotation medium pH value 8.5～9.5 separating effects are best.
According to main points (2), phthalic anhydride heating hydrolysis or phthalic acid half saponification, control saponification pH value 3.5～5 its objective is and utilizes the collecting effect of hydrogen phthalate radical ion to bastnaesite, guarantees that its saponified middle hydrogen phthalate radical ion content is greater than 75%; Aluminium salt consumption is wanted suitably, and excessive also have inhibitory action to bastnaesite, influences separating effect; Flotation medium pH value is too high or too low, and separating effect is poor.
The present invention compared with the prior art, technology is simple, medicament kind is few, and is inexpensive, good separation effect.And can obtain simultaneously the purpose rare-earth mineral to the total rare earth (TRE) mineral content greater than bastnaesite concentrate more than 95% and monazite concentrate, economic benefit and obvious social benefit, harmful element content is lower than sewage drainage standard in the tailing water.
The inventor had once carried out following test: with the baiyuneboite raw material, and 29.18% ,-0.074% millimeter grain size content 95.52% of rare earth grade, rare-earth mineral monomer 77.05%; Raw material mineral composition: bastnaesite 23.71%, monazite 17.38%, fluorite 22.23%, apatite 7.09%, barite 10.00%, magnetic iron ore 2.62%, hematite-limonite 10.86%, dolomite, calcite 2.94%, stone, feldspar, quartz 2.89% in achmatite achmite, the sodium, other is 0.28% years old.Rare-earth mineral separates the employing hydroximic acid collecting agent with impure mineral, sodium metasilicate and 210 foaming agents, in pH8.5～9.5, pulp density 40～45%, 30～35 ℃ of temperature, at 2A, process one roughing in the 1A flotation device, triple cleaning, be enriched to rare earth grade (REO) 65%, bastnaesite and monazite ratio 3: 2 are used phthalic anhydride heating hydrolysis saponified (saponification pH value 3.5～5) and alum, then under pH value 4.5～5 and normal temperature condition, adopting 12 liters of flotation devices to separate roughly selects, after recleaning and secondary are scanned, obtain bastnaesite concentrate grade (REO) 69.68% respectively, bastnaesite is to total rare earth (TRE) mineral content 95.59%; Monazite concentrate grade (REO) 66.03%, monazite in the open circuit flowage structure, obtain the detached job yield respectively more than 60% with rare-earth mineral total amount 96.47%.
With bastnaesite and the monazite concentrate that the present invention produces, satisfied the quality requirement of applications such as rare earth ore concentrate smelting and production bastnaesite polishing powder fully.
Claims (1)
1, the ore-dressing technique of FLOTATION SEPARATION bastnaesite and monazite, it is characterized in that adopting hydroximic acid collecting agent, sodium metasilicate and general foaming agent (as keto-alcohol oil), with mineral such as low-grade bastnaesite and monazites is raw material, under flotation pulp pH value 8.5-9.5 and normal temperature condition, separate, obtain high-grade bastnaesite and monazite (3: 2) bulk concentrate, saponified with phthalic anhydride heating hydrolysis or phthalic acid half, saponification pH value 3.5-5, as the bastnaesite collecting agent, with aluminium salt (alum, aluminum sulfate or aluminium chloride) as the inhibitor of monazite, under flotation medium pH value 4.5-5 and normal temperature condition, carry out separating of bastnaesite and monazite.
