 · Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at different points during a process involving preconcentration followed by direct reduction and magnetic separation. Then, slagtailing concrete composite admixtures were prepared from highsilica .

The invention provides a method for preparing sodium thiosulfate. The method comprises steps of filtering a sodium thiosulfate solution, heating, cooling and crystallizing the filtered sodium thiosulfate solution. According to the method, under conditions that pH is 11 and temperature is 100DEG C, 21% saturated sodium sulfite solution and sulphur powder are mixed according to .

roasting the ore or concentrate to burn off the carbon. All of these techniques are relatively expensive however, so the economic cutoff gold grade for refractory ores is somewhat higher than nonrefractory ores. The mining industry uses a "rule of thumb" of 80% gold recovery to define the transition from a refractory to a non

concentration, (b) the path length, (c) the wavelength and (d) the solvent. Absorbance is related to the concentration according to the BeerLambert law: A=ebc where ε is the extinction coefficient (M1cm1), b is the solution path length (cm) and c is the concentration (moles litre1).
