ABSTRACT:
Alkylaryl hydrocarbons having at least eleven carbon atoms, when used either alone or in combination with known sulfide collectors, result in enhanced recovery and selectivity when used as collectors for sulfide minerals. These alkylaryl hydrocarbons are generally derived from the alkylation of aromatic compounds with the appropriate olefin in synthetic processes. Isopropyl naphthalene appears foremost among these compound as an effective sulfide collector.
