Because natural silicates are potential sources of oligosiloxanes of the type QxMy, a collection of natural silicates of similar structure was used to obtain mainly Q 2 M 6 oligosiloxanes by trimethylsilylation. The tailings from silver and gold flotation beneficiation provide an important silicate source. The main silicate phase reactive to trimethylsilylation was found to be anorthite. Other minerals containing silicates with a structure similar to anorthite (labradorite and augite) were also used as a Q 2 M 6 source. This paper presents a full characterization of Q 2 M 6 as well as information related to the residual solids from the TMS reactions. Copyright © 2005 John Wiley & Sons, Ltd.
