    摘要： Caking of industrial alkali metal chlorides and mixtures containing them in storage is prevented and a flowable product is obtained by adding a hydrophilic and/or a hydrophobic material, in combination with a complex iron cyanide, on a hydroxyl group containing carrier to produce a permanent moisture content of at least 0.01 weight percent of water on the salt.

    摘要： There is prepared a powdery anticaking agent for inorganic salts based on (A) an iron cyanide complex, (B) a water insoluble inorganic, inert, finely divided hydroxyl group containing material or a material able to form this in the production of the anticaking agent, (C) hydrophobizing and/or (D) hydrophilizing materials in which (A), (C) and/or (D) are employed on component (B) as a carrier together with (E) water in an amount of 20 to 50 weight percent, preferable 35 to 45 weight percent. The composition is prepared by intensively mixing the carrier (B) in the corresponding ratio in the dry state with the active materials at room temperature and then adding to this mixture so much water that the active components go into solution and as such are absorbed on the carrier and regulating the pH to 7 to 9, preferably 7 to 8.

    摘要： A process is described for leaching gold and/or silver from ores or ore concentrates using an aqueous alkaline cyanide solution with addition of hydrogen peroxide. The addition of the aqueous H.sub.2 O.sub.2 solution is regulated and controlled through the concentration of the oxygen dissolved in the leaching solution, the leaching solution containing from 2 to 20 mg O.sub.2 and preferably from 7 to 13 mg O.sub.2 per liter. 0.5 to 5% by weight H.sub.2 O.sub.2 solutions are preferably added. The process is applicable both to leaching by agitation and to heap leaching, the addition of H.sub.2 O.sub.2 being regulated and controlled through measurement of the O.sub.2 concentration in the leaching solution and can also involve measurement in a measuring stream. Despite low consumptions of H.sub.2 O.sub.2 and NaCN, the gold yield is even increased in some cases and the leaching time shortened.

    摘要： In the detoxification of waste waters containing nitrite ions by means of hydrogen peroxide the addition of hydrogen peroxide is automatically controllable by adding the hydrogen peroxide continuously or in portions with continuous measurement of the pH and stopping the addition when no further reduction of the pH is caused by it. By control of the hydrogen peroxide addition through the change of the pH it is guaranteed that sufficient hydrogen peroxide is added to reach a complete detoxification of the waste water while on the other hand there is not wasted hydrogen peroxide unnecessarily.
