摘要:
The disclosure provides compositions for improving a froth flotation type separation and their use for froth flotation. The composition are in the form of a microemulsion containing water, collector and surfactant(s) to improve the effectiveness of the collector. The improvement allows for low dosages of collector to work as well as much greater amounts of non-microemulsified collector.
摘要:
The present invention relates to a process to treat magnetite ore containing less than 15 wt % of silica on total ore, the process containing a step of (froth) flotating in the presence of a collector composition that contains 80 to 100 wt % of at least one alkylethermonoamine, less than 20 wt % alkyletherdiamine, all wt % based on total weight of all amine components, and wherein the alkylethermonoamine is an alkylethermonoamine with a degree of branching higher than 1, the alkyl containing 11 to 17 carbon atoms, and further relates to the collector composition that can be used in the process.
摘要:
The invention concerns a process for enriching an iron mineral from a silicate containing iron ore by inverse flotation comprising the addition of a collector or collector composition comprising at least one of the compounds of formulae RC(0)N(Z-0-X-NH 2 ) 2 (la); RC(0)N(Z-0-X-NH 2 ) 2 H + Y - (lb); in which X is an aliphatic alkylene group containing 2 to 6 carbon atoms; Z is an aliphatic alkylene group containing 2 to 6 carbon atoms; Y - is an anion; and R is a saturated or unsaturated, linear or branched, aliphatic or aromatic moiety having between 7 and 23 carbon atoms. The invention also relates to the novel compounds according to formulae (la) and (lb), compositions comprising said compounds and the use of compounds and formulations as collectors for enriching of iron mineral.
