A process mineralogy approach to optimize

2020-10-1  The samples were taken from the molybdenite flotation circuit at the copper-molybdenum processing complex of Sungun. The flotation circuit of the plant consists of two 8-cell rows for the rougher flotation stage. The volume of each cell is 2.8 m 3 and of mechanical type. The cleaner stage consists of an 8-cell row, of the same type as rougher‘s mechanical cells.

Review of the flotation of molybdenite. Part I: Surface

2016-3-10  Depression of molybdenite in seawater and saline waters is mainly induced by the precipitation of colloidal magnesium hydroxide when pH is raised to depress pyrite. Other metal cations present in recycled process water can also reduce the flotation recovery of molybdenite (e.g., Al 3 +, Fe 2 +, Cu 2 + ions). The native floatability of molybdenite is highly depressed by natural polymers (starch,

Molybdenum an overview ScienceDirect Topics

Molybdenum disulfide (MoS 2) is the major source of raw material. Molybdenum disulfide is concentrated by flotation and transformed to an impure technical molybdenum trioxide (MoO 3) by means of roasting, which oxidizes the sulfur and removes it as gaseous sulfur dioxide [108].
