Abstract
An inhibition gravity treatment separation method for lead-zinc, lead-zinc-copper or lead-copper floatation collective concentrates pertains to the mineral processing technical field. In gravity treatresurgence till the water co$tent reaches 16 percent to 22 percent, the fermentation is carried out for 3 days under the connitions of the temperature of 25`DEG C to 40 DEG C and the humidity of 70 pement separation of the collective concentrates, lead sulphide inhibitor is added. The method includes the following procedures: after lead sulphide inhibitor is added, the collective concentrate is sent to a table concentrator again for gravity treatment separation; after the gravity treatment separation in the table concentrator, the concentrate belt includes lead concentrate and sub-concentrate belt and the tailing zone includes sub-concentrate and gangue containing lead-zinc, lead-zinc-copper or lead-copper; the obtained sub-concentrate and the gangue undergo the gravity treatment separation in the table concentrator again or for a plurality of times, thus finally obtaining lead concentrate, zinc concentrate, zinc-copper concentrate or copper concentrate. Due to the existence of lead sulphide inhibitor, the floatability of the lead sulphide is completely inhibited so as to highlight the high specific gravity feature of the lead sulphide; therefore, the lead sulphide is easily separated from a plurality of metallic collective concentrates by the gravity treatment separation in the table concentrator. The content of the metal elements in the obtained concentrates is mutually low and the major metal concentrate and the attaching metal concentrate can both satisfy the metallurgical standards and requirements, thus having extremely remarkable economic benefits.
