Leaching of molybdenum and arsenic from uranium ore and mill tailings

Hydrometallurgy, 1984
Abstract A sequential, selective extraction procedure was used to assess the effects of sulfuric acid milling on the geochemical associations of molybdenum and arsenic in a uranium ore blend, and the tailings derived therefrom. The milling process removed about 21% of the molybdenum and 53% of the arsenic initially present in the ore. While about one-

Research on Column Flotation of Sliming Molybdenum Tailings Using Ultrasonic Pre-Treatment

Applied Mechanics and Materials, 2014
In this paper, for the re-concentration of sliming molybdenum Tailings in Henan Province, a multi-parameter test is carried out using orthogonal method in the column flotation system with the ultrasonic pre-treatment. Two groups’ optimum parameters of ultrasonic pre-treatment are acquired through the analysis of orthogonal test results.

Phytotoxicity of Tailings Dam of the Dzhidinsky Tungsten–Molybdenum Combine (Western Transbaikalia)

2015
The phytotoxicity of tailings dam of the Dzhidinsky tungsten–molybdenum combine has been studied. It is established that the content of toxic chemical elements (Pb, Zn, As, Cu, Co, Mo, Ni, W) in technogenic sands is extremely dangerous; the total contamination index (Zc) is 425–500.
