Abstract

Селективные флокулянты содержат полимер, включающий повторяющиеся звенья одного или более акриламидных мономеров; повторяющиеся звенья одного или более мономеров, выбранных из гидроксиалкилалкилакрилата, аллилоксиалкилдиола, аллилоксиэтанола, триметилолпропаналлилового эфира и 2-гидроксиэтилакрилата; и, возможно, повторяющиеся звенья одного или более мономеров акриловой кислоты. Также раскрыты способы обогащения желательного минерала из руды, содержащей этот желательный минерал и пустую породу, включающие осуществление способа селективной флокуляции в присутствии одного или более селективных флокулянтов.
