Effect of Surfactant on Spherical Oil Agglomeration of Coal (RESEARCH NOTE)
author
Abstract:
In this paper, the results of the Spherical Oil Agglomeration of Abstract .45 micrometer superpits low grade co al pa rticles (Bagworth Colliery, U.K.) within a su spension are prese nte d.Demineralized agglomerates were recovered directly by sieving on a 106 micrometer sieve. Verygood reductions in the ash content of the feed coal samples were achieved. In order to reducethe high levels of the crude oil dosage comparatively, small quantities of surfactants were added t o the su spension. Of the va rious su rfactant s screened, Tr iton x.405 (non.ionic) proved to bevery efficient and a crude oil reduction of over 60 wt% was achieved for concentrates containing8 wt% ash.

Environmental protection has become the focus of world-wide research in the gold mining industry and favours the development of environmentaly sound processes, such as the Coal Gold Agglomeration (CGA) process, which is an alternative to existing gold processing methods, such as cyanidation and mercury amalgamation. The CGA process was developed and patented by the British Petroleum (BP) resear...

The main aim of this experimental work was to develop a separation process using micro- bubbles less than 100 µm in diameter. Micro-agglomerates were produced using 10kg crude oil/tone feed coal treated compared to 250 kg/tone feed coal treated for conventional spherical oil agglomeration. These micro-agglomerates were separated from the unagglomerated minerals by micro-bubble flotation. Colloi...
