| Abstract: | Low-graded phosphate ores from Rockland of Florida are usually processed by flotation in two stages in USA with concentrates obtained. The test focuses on searching for new reagent regime and processing parameters,and is conducted in a US prevailing processing circuit of one roughing and one cleaning with three types of home- made reagents Lsss, N- 1 and B-104. The result is satisfactory,totally meeting the requirements for index made by the US partner. |
