Process flowsheet development for recovering antimony

2013-8-1  To have an effective and efficient leaching of antimony from its minerals (e.g. tetrahedrite), it would be beneficial to the leaching process if the mineral particles of the concentrate are finely ground prior to the leaching step (Filippou et al., 2007, Awe et al., 2010, Awe and Sandström, 2010b). Moreover, high concentration of the alkaline ...

US3883345A - Process for the recovery of antimony -

A process for the recovery of antimony values from a material containing the same is described wherein the material is subjected to a controlled roasting step, the resulting calcine leached with an alkaline solution to extract antimony values and the antimony-pregnant solution acidified to precipitate antimony values. The roasting step is carried out in a reducing environment thus assuring ...
