Abstract
The invention consists of compositions for agglomerating wetted metal-containing ores. Such such compositions are: ______________________________________ General Ingredients % by Weight ______________________________________ A. A water-in-oil emulsion of a water- 10-45 soluble vinyl addition polymer which contains at least 10% by weight of the water-soluble vinyl addition polymer B. A polysaccharide 55-90 C. A water-soluble surfactant 0.001-10 D. Borax 0-15 ______________________________________ Also described is the use of these compositions for agglomerating wetted metal ore-containing materials are the products produced by such an agglomeration process.
