Description
Technical field
The present invention relates to a kind of floatation separation process, particularly relate to a kind of lithium beryllium separation of pulp concentrate technique.
Background technology
Normal and the beryl symbiosis of spodumene in the granite peamatite mineral deposit, the floatability of the two is close, and both FLOTATION SEPARATION are by a difficult problem that is ore dressing field.More to the research of Li-Be flotation at eighties of last century six the seventies both at home and abroad, and mainly lay particular emphasis on the flotation of spodumene, and the achievement in research report in this field was very few in recent years, the Patents that can find and documents and materials are also less.
On January 16th, 1973 disclosed United States Patent (USP)-" a kind of spodumene method for floating (publication number 3710934Wyman) ", under the condition of pH8～10, adopt the amine collector of 7～15 carbon numbers that gangue mineral is floated, product is realized the spodumene reverse flotation as the spodumene concentrate in the groove.Disclosed United States Patent (USP)-" the floatation processing contains lithium minerals (publication number 4098687Yan g) " on July 4th, 1978, the mixture that is ground to multivalent metal salts such as adding water miscible ferric nitrate in the lithium minerals ore pulp of suitable granularity and waterglass is sized mixing, then add the oleic-acid collecting agent and carry out flotation, froth pulp is high-grade spodumene concentrate.On March 19th, 2003, disclosed patent-" Beryl dressing process (publication number 1403207) " provided a kind of beneficiation method of beryl, made the valuable constituent in the mineral obtain sorting in weak alkaline medium.On March 26th, 2008 disclosed patent-" spodumene ore heavy medium-strong-magnetic ore-dressing technology method (publication number 101147888) ", spodumene ore reduction is become the spodumene ore of most of monomer dissociation, by washup flush away sludge, again with feed heavy medium cyclone after dense media mixes and sort.
Since the last century the eighties, to the FLOTATION SEPARATION of lithium beryllium bulk concentrate, " three alkali (Na have usually been adopted
