摘要： The invention relates to a method of processing the waste sludge obtained in purification facilities for phosphoric acid produced by the wet process. The composition of this sludge is such that it cannot be utilized for any purpose in this state. It is known that sludge from wet phosphoric acid purification facilities contains different quantities of certain substances, the concentrations being such that these substances may not be allowed to mix with surface water or ground water under any circumstances, not even in the case of dumps. A typical composition of such waste sludge is as follows:______________________________________ Fe 9.0% by weight P.sub.2 O.sub.5 21.0% by weight CaO 6.2% by weight SiO.sub.2 12.5% by weight MgO 5.8% by weight Al.sub.2 O.sub.3 2.7% by weight Cr.sub.2 O.sub.3 0.7% by weight V.sub.2 O.sub.5 0.6% by weight Na.sub.2 O 18.0% by weight K.sub.2 O 0.3% by weight F 1.7% by weight C 2.5% by weight S 0.3% by weight Remainder* 18.7% by weight 100.0% by weight ______________________________________ *The remainder consists mainly of hydration water and carbonate that did not decompose at a temperature of 105.degree. C.

摘要： A method for preheating the oxygen used in converters. Steam which is already available in the usual steel manufacturing plant, is used to preheat the oxygen. The steam may be generated from waste gas produced in an converter process. A heat exchanger which may be placed into an oxygen supply line, feeds into a line of the blast lance. This heat exchanger may be placed between the feed line to the blast lance and shut off and control devices in the oxygen supply line. A connector in the oxygen supply line may be located between the heat exchanger and the feed line to the blast lance, and may be heat-insulated.
