Abstract
The process for agglomerating and passivating the pulverulent used material and/or the pulverulent fines resulting from the production of organohalosilanes, comprises the mixing of this used material and/or fines with a binder chosen from aluminum silicates and the production of a solid agglomerated product by compression in a press, such as a roll type briquette machine. The invention also relates to the agglomerated product thus obtained and to its use in the recovery of certain metals, such as silicon and copper.
Claims13
A process for agglomerating and passivating pulverulent used material and/or pulverulent fines resulting from the production of organohalosilanes, said process being conducted in the absence of free water, the process comprising:
- (i) forming a mixture of used material and/or pulverulent fines resulting from the production of organohalosilanes and a binder comprising an aluminum silicate by mixing said used material and/or fines with said binder;
- (ii) producing a solid agglomerated product by compression of said mixture in a press.
A solid, inert and non-self-heating agglomerated product which comprises a compressed mixture of (1) used material and/or residual fines resulting from the production of organohalosilanes and (2) an aluminum silicate, wherein said agglomerated product does not comprise free water.
