Beneficiation test report of molybdenum ore in Fukang molybdenum processing plant in Luonan County, Shaanxi Province


The purpose of the test is to provide a reasonable beneficiation process and economic and technical indicators for the mine through mineral processing test research, and provide reference for resource development and utilization.

The molybdenum ore molybdenum a thick, two sweep, eight fine, Molybdenum tailings Comprehensive Recovery pyrite, test index: 42.75% molybdenum concentrate containing molybdenum, molybdenum recovery of 76.04%, 48.17% sulfur concentrate sulfur, sulfur The recovery rate was 78.33%.

The molybdenum ore minerals are seven kinds of metals: molybdenite, pyrite, copper ore, bornite, magnetite, hematite, limonite. Seventeen species of gangue minerals: quartz , feldspar , diopside , tremolite , actinolite , biotite , sericite, chlorite, calcite , dolomite, epidote, talc , brucite , sea Stone, slate, zircon , graphite .

Due to the presence of carbon and easy-floating gangue (sericite, talc, pyroxene) in the molybdenum ore, the foam is sticky during the beneficiation process, which affects the beneficiation index.

Molybdenum ore is the main target mineral of this test, and molybdenum ore is more unevenly dispersed in the ore. The single crystal is mainly composed of a small amount of polycrystalline crystals. A small amount of molybdenum ore is interspersed in the fracture of the ore-bearing rock. Some molybdenum ore can be encapsulated in the pyrite grains. See also for pyrite. Interpolation and intercalation, the mineral crystal size is small, which is mainly the main reason affecting the grade and recovery rate of molybdenum concentrate.
