From time to time the liquors were run into the cistern then boiled down the concentrated solution would deposit on cooling green crystals of copperas - ferrous sulfate - feso47h2o a greater yield could be obtained by adding scrap iron to the hot solution the crystals were often gathered on twigs where they formed like barley sugar
Most of the ferrous sulphate wastes are treated with lime to make them alkaline the solutions are then transferred to lagoons where soluble ferrous hydroxide oxidises to ferric hydroxide which precipitates aided somewhat by water evaporation in this way iron is
Jan 01 2003 ismael and carvalho 1996 ismael and carvalho 1999 and ismael (1999) studied the extraction of iron with a mixture of dehpaprimene jmt2-octanol diluted in shellsol t some of the experiments were carried out with an aqueous solution containing 15 gl of fe 3 and different mixtures of the above extractants satisfactory results are achieved with the mixture06 m dehpa 027 m
