    Abstract: A mixture consisting essentially of: a) one or more dicarboxylic acid esters of the formula I ROOC-A-COOR (I) in which the radicals R independently of one another are alkyl groups having 1 to 20 carbon atoms and A is alkylene having 1 to 20 carbon atoms, alkenylene or alkynylene each having 2 to 20 carbon atoms, cycloalkylidene or cycloalkenylidene each having 5 or 6 carbon atoms or phenylene and b) the product (II) of the reaction of a triglyceride based on carboxylic acids having 2 to 30 carbon atoms and ethylene oxide and/or propylene oxide in the presence of a base, which is useful for the production of crop protection compositions, for herbicidal crop protection compositions, and for controlling undesired plant growth, and spray mixtures comprising the compositions.

    Abstract: Disclosed is an aqueous cyanide-containing composition comprising at least one non-ionic surfactant, wherein the nonionic surfactant, in a concentration of from 0.01 to 0.2% by weight in an aqueous solution adjusted to a pH of from 9.8 to 10.2 with NaOH, at 23°C, leads to a reduction in the contact angle on glass after 1 second by at least 10°. Also disclosed is a process for extracting metals from materials comprising these metals, comprising: (a) provision of an optionally milled metal-containing material; (b) provision of a composition as described above; (c) bringing of the metal-containing material into contact with the composition in the presence of an oxidizing agent, and obtaining a mother liquor enriched with metal cyanide complexes.
