  • Asbestos waste destruction and valorization method
    Patent number: 11577112
    Abstract: A method for destructing and valorizing an asbestos waste including the steps of: determining the asbestos mineralogical group contained in the waste, performing a treatment on the waste which includes of: an acid treatment when the waste comprises only a chrysotile, a base treatment when the waste comprises only an amphibole, the acid treatment followed by the base treatment when the asbestos waste includes a mixture of a chrysotile and an amphibole, and valorizing at least one of the products obtained on completion of the performing of the treatment. An embodiment also concerns a treatment of a chrysotile waste through an acid treatment followed by a thermal treatment.

  • Controlled dissolution of quartz
    Patent number: 5397430
    Abstract: Quartz sections having a surface condition as polished as possible are prepared by controlled dissolution by placing said quartz sections in a bath of a quartz solvent or a mixture of solvents, wherein the bath is basic and comprises an alkaline hydroxide or fluoride, or ammonium hydroxide, or a mixture of these compounds; and conducting controlled dissolution of the quartz sections at atmospheric pressure.

  • Process for dissolution of a crystalline material
    Patent number: 5275697
    Abstract: The present invention relates to a process for controlled dissolution of a crystalline material consisting of a number of kinds of ions, in a solution containing a solvent for the crystalline material. Before dissolution, the solution contains at least two kinds of ions of the crystalline material. The molar concentration of ion of each kind is higher than zero and lower than the molar concentration of ion of each kind which the solution would have at saturation if it contained all of the constituent ions of the crystalline material, under the temperature and pressure conditions of the dissolution.
