Abstract:Materials of low specific gravity had to be removed from available local aggregate for the Beechwood development of the New Brunswick Electric Power Commission in order to produce concrete with satisfactory resistance to freezing and thawing. Heavy media separation plant used suspension of ferrosilicon and magnetite in water, removing aggregates which floated in the medium whose specific gravity was about 2.6. Aggregates which sank were cleaned and retained for concreting. Salvage and reuse of the suspension medium are explained.
