Spherical Oil Agglomeration (SOA)/ Colloidal Gas Aphrons (CGA) Flotation

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...

Estimation of barium sulphate in faeces by emission flame photometry.

Received for publication 12 July 1968. ashed in a muffle furnace at 600'C for at least three hours. Of the acid ammonium sulphate, 10 ml, and 30 ml of water are added to the ashed sample, and after warming to dissolve soluble material the contents are decanted with washing into a 50 ml centrifuge tube, the BaSO4 being washed into the tube as far as possible. The tube is centrifuged for 5 min, t...

Effect of Surfactant on Spherical Oil Agglomeration of Coal (RESEARCH NOTE)

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...

Barium Sulphate Absorption and the Serum Diagnosis of Syphilis

The so-called syphilitic antibodies can be removed from a serum by means of absorption with barium sulphate. The removal is due either to an adsorption or a mechanical absorption. The activity of the syphilitic antibodies is thereby unimpaired. The readiness with which the absorption is accomplished with barium sulphate varies considerably with different syphilitic sera. That barium sulphate ex...
