The invention relates to a method for the hydrometallurgical recovery of lithium from the lithium manganese oxide-containing fraction of used galvanic cells.

Method for the hydrometallurgical recovery of lithium from the lithium manganese oxide-containing fraction of used galvanic cells

A method for coating a metallic surface with an aqueous composition for pretreating before applying another coating or for treating said metallic surfaces. The method is characterized in that the composition contains, in addition to water; a) at least one hydrolyzable or at least partially hydrolyzed fluorine-free silane, and; b) at least one hydrolyzable or at least partially hydrolyzed fluorine-containing silane. The invention also relates to corresponding compositions.

Method for coating metallic surfaces with a mixture containing at least two silanes

A process for the treatment or pretreatment of containers made of aluminum, aluminum-containing alloys, magnesium-containing alloys, iron-containing materials such as steel, coated iron-containing materials such as galvanized steel, or aluminum alloys, tinplate, brass or bronze, in particular the treatment or pretreatment of bags, tubs, bottles, cans, canisters, casks or tubes, wherein the process steps for the treatment or pretreatment take place at the same time as the application of the lubricant, with the agent used for the pretreatment or treatment, which also contains or is a lubricant, not essentially consisting of titanium or zirconium with fluoride and polymer, the lubricant possibly being formed first in the agent for the pretreatment or treatment or in the formation of the coating produced therefrom.
