Method for recovering cyanide from a barren solution

Номер: US20170081202A1
Автор: Herve Buisson, Kashi Banerjee
Принадлежит: Veolia Water Solutions and Technologies Support SAS

A process is disclosed for recovering cyanide used to leach gold or silver from ore. In the course of leaching gold or silver from ore, a barren solution is generated. A portion of the barren solution containing sodium cyanide is recycled to the cyanidation process while blowdown from the barren solution is subjected to pre-treatment, UV photodissociation and pH adjustment. Ultimately, a volatile hydrocyanic acid is formed and is absorbed into a sodium hydroxide solution through the employment of a gas-filled membrane. This forms sodium cyanide that can be recycled and used in the cyanidation process to leach gold or silver from ore.

The present disclosure discloses a method for preparing a polyether polyol in a continuous reaction cycle. In the method, a low molecular-weight alcohol is polymerized with an alkylene oxide to obtain a low molecular-weight polymer. The low molecular-weight polymer is used as an initiator to react with the alkylene oxide and the low molecular-weight alcohol in the presence of a DMC catalyst and an acid promoter to obtain an intermediate-target polymer. A portion of the intermediate-target polymer is used for producing the target polymer, and the other portion is recycled for reproduction of the intermediate-target polymer.

The invention provides an oxygen Andrussow process for production of hydrogen cyanide from a methane-containing feedstock such as natural gas in the presence of oxygen and ammonia over a platinum catalyst, wherein the production of byproduct organonitrile impurities, such as acrylonitrile, is reduced. Limiting the content of C hydrocarbons in the methane feedstock in the oxygen Andrussow process, in contrast to the air Andrussow process, has been found to reduce formation of organonitriles, such as acrylonitrile. The organonitrile impurities can require additional processing for removal cause fouling of equipment, and can also contribute to hydrogen cyanide polymerization. Reduction of C+ hydrocarbon levels to less than 2 wt %, or 1 wt %, or less than 0.1 wt %, in the methane can provide an improved yield of higher purity HCN. Reduction of C+ hydrocarbon levels also solves the problem of polymer buildup in process equipment, reducing downtime required for cleaning when higher C+ hydrocarbon levels are present in the reaction feed. 1.
