theextractionofgoldfromcyanidesolutions bystrongandweak using strongbase resins to.extract gold from cyanide solution1176;.they concluded that the nonselectivity of gold absorption, coupled with the high cost ofelution (ammonium thiocyanate and acidified acetone were tested aseluants), rendered theprocess unfavourable as compared with zincprecipitation

differentiation between zinc, aluminium, and magnesium $\ce{al^3+}$ the chemical aluminion can be added to a solution to test for the presence of $\ce{al^3+}$ ions. this is done by first adding $\ce{naoh}$ to the solution to precipitate out $\ce{al(oh)3}$. in the presence of aluminon, the $\ce{al(oh)3}$ forms a lake dye through chemisorption, causing a pinkish red precipitate to form.
