Abstract
Fremgangsmåte for fremstilling av apatitkonsentrat.Process for the preparation of apatite concentrate.
Description
Oppfinnelsen vedrører en fremgangsmåte for fremstilling av fosfatkonsentrat med apatit som mineralkomponent, fremstillet for kommersiell anvendelse. The invention relates to a method for producing phosphate concentrate with apatite as mineral component, produced for commercial use.
Apatitkonsentrat har hatt praktisk anvendelse - undersøkt i laboratorier og ved konsentrat pilot plan. Apatite concentrate has had practical application - investigated in laboratories and by concentrate pilot plan.
F remstilling av mineraler for f lott ering..'Production of minerals for flotation..'
Knusing:Crushing:
Råmalmen utsettes for egnet knusning omfattende: knusing, homogenisering og møllebehandling inntil apatiten er fri fra. gjenværende oksydasjonsprodukter ved hjelp av varlig utstyr. De- sludging: Av den malte pulp elimineres den ultrafine granulo-mere fsaksjon (en operasjon teknisk kjent, som de-sludging) . Magnetisk separering: Den magnetiske fraksjon som består av magnetitad-skilles ved vanlige magnetiske separatorer. The raw ore is subjected to suitable crushing, including: crushing, homogenisation and mill processing until the apatite is free from. residual oxidation products using safe equipment. De-sludging: The ultra-fine granulomer fraction is eliminated from the milled pulp (an operation technically known as de-sludging). Magnetic separation: The magnetic fraction consisting of magnetitad is separated by ordinary magnetic separators.
F lotering:Lottery:
Konsentrering av selve apatiten utføres ved hjelp av flotasjon i.to trinn, som beskrevet' nedenfor : Concentration of the apatite itself is carried out by means of flotation in two stages, as described below:
. Anionisk. f Iotas jon:. Anionic. f Iota's ion:
Kondisjonerende - til pulpen etter fremstilling, settes trykkeoppløsning av oksydasjonsmineraler sammensatt av gelatinisert stivelse i en høy prosentdel'av faste stoffer (50%) 'ved hjelp av mekanisk blanding. Conditioning - to the pulp after production, pressure solution of oxidation minerals composed of gelatinized starch in a high percentage of solids (50%) is added by mechanical mixing.
Apatitflotering:Apatite flotation:
Pulpen,'omhyggelig kondisjonert, ekspanderes med vann i et alkalisk'medium og som alkalinitetsregulator kan det benyttes natriumhydroksyd, ammoniumhydroksyd eller natriumkarbonat . The pulp, carefully conditioned, is expanded with water in an alkaline medium and sodium hydroxide, ammonium hydroxide or sodium carbonate can be used as an alkalinity regulator.
Ved å tre inn i fIotasjonsutstyret antar pulpen betingelsene for anionisk type kollektor. By entering the flotation equipment, the pulp assumes the conditions of an anionic type collector.
På'denne måte oppnås et konsentrat som er rikt på apatit og som oksydasjonsmineral fjernes vesentlig magnetit, limonit, vermikulit, silikater, som pyroksenic og amfibol feldspat ved siden av alternerende mineraler som sekundært aluminium og jernfeldspat. Kationisk flotasjon. In this way, a concentrate is obtained which is rich in apatite and, as an oxidation mineral, magnetite, limonite, vermiculite, silicates such as pyroxenic and amphibole feldspar are removed, alongside alternating minerals such as secondary aluminum and iron feldspar. Cationic flotation.
Konsentrasjonen oppnådd i første fIotasjonstrinn .har en meget fin forurensning av vermiculit, som idet den er opp-løselig'i sterke, syrer, er en kilde for aluminium og jern,, så-ledes at dette produkt ikke kan utnyttes ved fremstillingen av superfosfater og MAP (mono-ammoniumfosfat). Dette meget fine vermiculit, samlet av klassifisering, krever etterfIotasjons-trinn for eliminering. Etter nøytralisering av stoffene pas-serer konsentratet igjennom et kondisjoneringstrinn, hvorved, apatityngelstoffet■ tilsettes omfattende en oppløsning av gelatinisert stivelse ved hjelp av mekanisk blanding med en høy prosent av faststoff (50%). Den anvendte kollektor i oppsamlingen av vermiculit er av kationtypen i området- nøytralt pH til alkalisk (7,0 til 10,5). Den er i stand til å anvende som pH-regulator et hvilket som helst hydroksyd som natriumhydroksyd, ammonium-hy'droksyd, natriumkarbonat og andre. Det oppnås som flotasjons-produkt et konsentrat som er rikt i meget fin vermiculit og ikke-samlet rikt i apatit fritt for vermiculit. The concentration obtained in the first flotation stage has a very fine contamination of vermiculite, which, as it is soluble in strong acids, is a source of aluminum and iron, so that this product cannot be used in the production of superphosphates and MAP (mono-ammonium phosphate). This very fine vermiculite, collected by classification, requires a post-flotation step for elimination. After neutralization of the substances, the concentrate passes through a conditioning step, whereby the apatite yellow substance ■ is added comprising a solution of gelatinized starch by means of mechanical mixing with a high percentage of solids (50%). The collector used in the collection of vermiculite is of the cation type in the range - neutral pH to alkaline (7.0 to 10.5). It is capable of using as a pH regulator any hydroxide such as sodium hydroxide, ammonium hydroxide, sodium carbonate and others. A concentrate rich in very fine vermiculite and unaggregated rich in apatite free of vermiculite is obtained as a flotation product.
" I lys av det faktum at dette fIotasjonstrinn har til hensikt eliminering av en meget fin fraksjon av vermiculit hindrer intet dets eliminering i første fIotasjonstrinn, men på bekostning av'et meget stort tap av apatit, benyttes et annet trinn. "In light of the fact that this flotation step aims at the elimination of a very fine fraction of vermiculite, nothing prevents its elimination in the first flotation step, but at the cost of a very large loss of apatite, another step is used.
