In practice, sulfide flotation plants operate at pulp potentials that are in the range of +50 to +200mV versus SHE (Grano, 2004) and the value depends on the pulp pH, type and quantity of sulfide minerals, the type and quantity of grinding media (Rao et al., 1976), and the amount of air–pulp contact in and after the grinding circuit (Teague et al., 1999b).

Fluor Has More Than 60 Years of Mining Process Expertise. Through their collective knowledge, experience and track record in studies and project execution excellence, Fluor's Mining team assists in the long-term productivity and profitability of our clients' mining assets.high pressure grinding (hpgr) During high-pressure grinding in roller presses coarse materials, such as cement clinker, ore or limestone, are briefly subjected to very high compressive forces. The sheets thus produced can be ground and thus reduced to the desired final particle size with minimum energy requirements.

Cutting data and tool path programming. Always position the cutter off-centre in relation to the milled surface; With KAPR 90° long edge cutters or end mills, use low radial immersion: max a e = 25% DC and high axial cut: max a p = D e In face milling, use a small depth of cut, a p, and high feed, f z, with round inserts or high feed cutters with small entering anglesThree multi-investigator groups that operate principally in the TB/HIV space: The South African TB Vaccine Initiative (SATVI), which includes Mark Hatherill (Director), Tom Scriba (Deputy Director) and Elisa Nemes; The Wellcome Centre for Infectious Diseases Research in Africa (CIDRI-Africa) which includes Robert Wilkinson (Director), Graeme Meintjes, Catherine Riou and Anna Coussens
