Description
Przedmiotem wynalazku jest sposób flotacji kopalin uzytecznych glównie siarczków miedzi oraz cynkui olowiu z zastosowaniem acetalu jako odczynnika spieniajacego.Do flotacji kopalin uzytecznych stosowane sa jako od¬ czynniki spieniajace substancjepowierzchniowo aktywne, obnizajace napiecie powierzchniowe i tym samym wytwa¬ rzajace piane dwufazowa. Wytworzenie piany umozliwia przeprowadzenie rozdzialu kopaliny na koncentrat zawie¬ rajacy mineral uzyteczny oraz odpad zawierajacy skale plonna.Najczesciej jako spieniaczy uzywa sie alkoholi, znane sa równiez jako spieniacze te z acetali, które wykazuja wlas¬ nosci powierzchniowo czynne, I tak stosuje sie wyzsze alkohole alifatyczne zawierajace w drobinie 5 i wiecej atomów wegla, oraz acetale otrzyma¬ ne w wyniku reakcji aldehydówz alkoholami zawierajacy¬ mi co najmniej 5 atomów wegla, w tym acetale dwualde- hydów.Proponowane w tych opisach patentowych spieniacze bedac odczynnikami powierzchniowo czynnymi wytwa¬ rzaja piane nawet w nieobecnosci mineralu, co stanowi powazna wade tych odczynników. Do piany przedostaja sie skladniki nieuzyteczne i tym samympogarsza sieselek¬ tywnosc procesu flotacji. Wskutek tego zmniejsza sie zna¬ cznie stezenie mineralu uzytego w koncentracie. Dotych¬ czas sadzono, ze wlasnosci powierzchniowo czynne, a wiec zdolnosc odczynnika dopienienia jest warunkiem koniecz¬ nym dla zachodzenia flotacji. Przeprowadzone przez nas badania pozwolily stwierdzic, ze acetale aldehydu mrów^ kowegoi octowego z nizszymi alkoholami o wzorze R/OCn H2n + 1/2 przy czym n = 1 - 4 nie posiadajac wlasnosci powierzchniowo czynnych, w warunkach flotacyjnych da¬ ja piany trójfazowe (otrzymuje sie piane jedynie w obec¬ nosci mineralu uzytecznego) zatem sa pozbawione wad oczynników powierzchniowo czynnych.Dzieki zastosowaniu do flotacji rudy miedzi acetali otrzymano koncentraty mniej zanieczyszczone niz przy uzyciu klasycznego odczynnika spieniajacego L-terpineo- lu przy podobnych uzyskach miedzi w koncentracie. Pro¬ wadzenie flotacji rud cynkowo-olowiowych z tymi odczyn¬ nikami zwieksza selektywnosc rozdzialu.Zalety acetali we flotacji rud miedziwynikaja jednozna¬ cznie z przedstawionego ponizej przykladu.Przyklad: Przy zuzyciu do procesu 60 g/t acetalu otrzymanego z aldehydu octowego i alkoholu propylowego oraz zbieracza (ksantogenianu 120 g/t) otrzymano naste¬ pujace srednie wyniki wzbogacenia: zawartosc miedzi w odpadach wynosila 0,29% wagowych Cu. Koncentrat zawieral 33,7% wagowych Cu. Przy uzyskach miedzi 91,7% wagowych Cu.Wyniki te otrzymano przy dostatecznie dlugim prowa¬ dzeniu procesu flotacji, tak ze mozna bylo wykazac ich istotnosc statystyczna. PLThe subject of the invention is a method of flotation of useful minerals, mainly copper sulphides and zinc and lead, with the use of acetal as a foaming agent. For flotation of useful minerals, surface-active substances are used as foaming agents, reducing surface tension and thus generating a two-phase foam. The production of foam enables the separation of the mineral into a concentrate containing a useful mineral and a waste containing a yield rock. Alcohols are most often used as foaming agents, they are also known as acetal frothers, which have surface active properties, and so are higher aliphatic alcohols containing 5 or more carbon atoms in the particle, and acetals obtained by reaction of aldehydes with alcohols containing at least 5 carbon atoms, including acetals of dialdehydes. The foaming agents proposed in these patents, being surfactants, produce foams even in the absence of a mineral, which is a serious drawback of these reagents. Inert components get into the foam and thus reduce the selectivity of the flotation process. As a result, the concentration of the mineral used in the concentrate is significantly reduced. Until now it was believed that the surface-active properties, and therefore the ability of the foaming reagent is a necessary condition for the flotation to occur. Our research allowed to state that acetals of formaldehyde and acetic aldehyde with lower alcohols of formula R / OCn H2n + 1/2, with n = 1 - 4 having no surfactant properties, gave three-phase foams under flotation conditions (obtained They are froth only in the presence of a useful mineral), therefore they are free from the disadvantages of surfactants. Due to the use of acetals for the flotation of copper ore, concentrates were obtained that were less contaminated than with the use of the classic L-terpineol foaming reagent at similar copper yields in the concentrate. Flotation of zinc-lead ores with these reagents increases the selectivity of the separation. The advantages of acetals in the flotation of copper ores are equal to the example presented below. Example: Using 60 g / t of acetal obtained from acetaldehyde and propyl alcohol in the process and collector (xanthate 120 g / t), the following average enrichment results were obtained: the copper content of the waste was 0.29% by weight of Cu. The concentrate contained 33.7 wt% Cu. At the copper recovery of 91.7% by weight of Cu. These results were obtained with a sufficiently long conduct of the flotation process, so that it was possible to prove their statistical significance. PL
