     at sarcheshmeh, the expansion plant (no. two) was established with large mechanical cells and flotation columns. molybdenum grading 0.025 plays a significant role in the economy of sarcheshmeh. while both plants treating the same ore, comparing with the old plant, mo recovery in the expansion plant was found to be 7-10% lower. thus an investigation was conducted to analyze the reasons of this difference. samples were collected from 11 points of the flotation circuit of the plant 2, and mo grades and solids concentration of the samples were balanced. in this work the effects of mineralogy, feed grade, flotation reagents, grinding and degree of liberation on molybdenite recovery is investigated. results indicated that, mo grade in feed and mo recovery are positively correlated and rougher cells are responsible for most of the mo losses which is due to locked molybdenite particles. additionally, a reverse relationship between mo recovery and existence of an isomorphic mineral (cufe2s7) was observed.
