摘要： A method for preparing an anion adsorbent may be provided, which comprises the steps of: mixing at least two metal salts with each other, thereby forming a stack structure in which cationic compound layers and anionic compound layers containing anions and water of crystallization are alternately stacked on one another; performing a first heat treatment on the stack structure to expand between the cationic compound layers, thereby preparing a preliminary anion adsorbent; and performing a second heat treatment on the preliminary anion adsorbent to remove the anions and the water of crystallization from the anionic compound layers while allowing at least one of the anions to remain, thereby preparing the anion adsorbent.

摘要： The invention pertains to a method for reduction of the cyanide content of a metals-containing wastewater fraction by contacting a wastewater fraction comprising cyanide compounds and metal compounds, with a metals content of at least 100 ppm, with hydrogen peroxide and a solid catalyst comprising at least 50 wt.% of a copper salt with a solubility of less than 10 exp(-5) mol/liter (in water at 20°C, 1 atm).
It has been found that when a solid catalyst comprising at least 50 wt.% of a copper salt with a solubility of less than 10 exp(-5) mol/liter (in water at 20°C, 1 atm) is used in combination with hydrogen peroxide in the reduction of the cyanide content of a cyanide compound-containing wastewater fraction having a metal compound content of at least 100 ppm, a method is obtained which shows an efficient removal of cyanide compounds from a difficult to treat fraction.
摘要翻译：本发明涉及通过使包含氰化物化合物和金属化合物的金属含量至少为100ppm的废水部分与过氧化氢和固体催化剂接触来降低含金属废水部分的氰化物含量的方法，所述固体催化剂包括至少50重量％的溶解度小于10埃（-5）摩尔/升的铜盐（在20℃的水中，1个大气压）。已经发现，当组合使用包含至少50重量％的溶解度小于10埃（-5）摩尔/升（在20℃的水中，1个大气压）的铜盐的固体催化剂时与过氧化氢相比，含有金属化合物含量至少为100ppm的含氰化合物的废水馏分的氰化物含量降低，得到了从难处理馏分中有效除去氰化物的方法。

摘要： This invention relates to a method of removing cyanide in the form of free cyanide (cyanide ions i.e. CN') and weak acid dissociable cyanide (WAD) from an aqueous stream. WAD is cyanide complexed with metals such as Cu. The method finds particular application in removing cyanide from a tail stream from a carbon in leach (CIL) mining operation. The method of the invention is carried out by contacting an aqueous stream containing cyanide with carbon, under conditions wherein the Eh (oxygen reduction potential (ORP) measured in mV) of the aqueous stream is O or above. Advantageously the pH of the solution is buffered to from 7 - 9.
