Jun 11, 2021· The crushing of molybdenum ore generally uses a three-stage one-closed-circuit process, and the final product size is 12-15 mm. Usually use the ball mill or rod mill-ball in the ore milling process. But there are also some processing flows adapted to use a semi-self-grinding process. Flotation adopts priority flotation method.

Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability. Further, because optimum moly flotation pH is at 7-8 while optimum copper selectivity is typically in the 9 ...

The invention discloses a flotation separation method for molybdenite and galena, which comprises the following steps of: 1, rough grinding; 2, rough selection and scavenging for obtaining lead-containing molybdenum rough concentrate; 3, regrinding after a certain amount of active carbon is added into the lead-containing molybdenum rough concentrate; and 4, multiple selection: selecting the ...

A process for the separation and recovery of molybdenite from molybdenum concentrates which comprises treating the concentrate with a lignin sulfonate and subjecting the lignin sulfonate-concentrate mixture to froth flotation to separate copper sulfides, iron sulfides and insolubles present in the pulp concentrate and increase the molybdenum concentration.

Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

It has played a positive role in expanding the raw material base of the copper and molybdenum industry because it enables new poor deposits to be mined and the medium- and low-grade ore from ...

Jun 11, 2020· During the flotation process, it use the CNFREE flotation chemicals and got good effect. Process Indicator. As a result, the grade and recovery of molybdenum flotation concentrates were 45% and 85% respectively, while those of tungsten flotation concentrates were both 65%. Comprehensive analysis showed that the project was relatively lucrative.

May 05, 2016· Molybdenum Ore Processing by Flotation. This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue. It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores.
