  • Froth Flotation - Metallurgist Mineral Processing Engineer

    Flotation operators must react and make changes without always understanding the primary cause for the observed decline in metallurgical performance. Thus flotation is often viewed as an Art rather than as a Science. Steps Involved 1. Grinding the ore fine enough so valuable mineral particles become liberated from the waste

  • Flotation - an overview ScienceDirect Topics

    Flotation is widely used to separate valuable minerals from the rock and fine coal particles from clay, silt, shale and other ash-producing matter. It is usually preceded by crushing and grinding the ore to liberate valuable particles in a host rock, and may be followed by metallurgical processes.

  • Reducing the Daily Grind - Features - The Chemical Engineer

    Apr 29, 2021  One of the reasons for energy-intensive comminution in mining is mineral flotation. It is typically the first process that physically separates valuable minerals from waste rock. The flotation product is a low-grade concentrate that represents a small fraction (2–5%) of the ore feed.

    Tails from the flash flotation cells are recycled back to the ball mills for further grinding. The target final product grind size from the milling circuit is 80% passing 150 µm, although increased throughput rates in 2011 and 2012 resulted in grind size P80 coarsening to 170 to 190 µm at times.
