1.用酸液溶浸鎂钛生产的殘料,再用菱鎂矿中和二次溶液。此法的特点能利用各种殘料(固态的,液态的和气态的)并从殘料中提出有用成分。鎂鈷生产中的固体殘料要分别进行处理。鎂生产的殘料用冷凝廢气肘得到的盐酸进行溶浸,而钛生产的殘料用中性洗滌水(处理鎂殘料时洗滌金屬氫氧化物得出的洗滌水)溶浸。 2.方法与1.相同,不同点是:为了使铁氧化,溶浸铁生产的殘料得出的溶液再用氯处理,然后从其中析出二氧化钛。 3.方法与1.相同,不同点是:为了制取硫酸铁和硫酸鋁,用氯压縮机的廢料——硫酸处理由鎂生产的殘料得出的金屬氫氧化物。
1. Magnesium leaching solution with magnesium leftover material, then magnesite and the secondary solution. This method is characterized by the use of a variety of residual materials (solid, liquid and gaseous) and from the residual material proposed useful composition. Solid waste in the production of magnesium and cobalt to be treated separately. Magnesium produced residues are leached with hydrochloric acid obtained by condensing the exhaust elbow and the titanium produced residue is leached with neutral wash water (wash water obtained by washing the metal hydroxide while treating the magnesium residue). 2. The method is the same as 1. except that in order to oxidize iron, the solution resulting from the production of iron-leached iron is treated with chlorine and the titanium dioxide is then precipitated therefrom. 3. The method is the same as 1. except that in order to produce iron sulphate and aluminum sulphate, the metal hydroxide derived from the residue of magnesium is treated with sulfuric acid of a chlorine compressor.
