    CLASS I NEW SULFIDE MINERAL COLLECTOR CHEMISTRY BASED ON CHELATIONCLASS II. NEW SULFIDE MINERAL COLLECTOR CHEMISTRY BASED ON REDOX MECHANISMSOME EXAMPLES OF NEW PRODUCT USAGEThe first of the chemistry families is based on using chelation chemistry. To incorporate chelation chemistry in a mineral collector is not a new concept. The problem with the published work in this area is that there clearly is a very poor correlation between chelation as practiced in solution chemistry (which is well known and where the ions to be captured have minimal restrictions on mobility, configuration capture angles, etc.) versus chelation and subsequent hydrophobe development on a mLive Chat
  • The Flotation of Sulfide Minerals Electrochemical Aspects.

    The Flotation of Sulfide Minerals Electrochemical Aspects. Selectivity in sulfide flotation arises from the nature of the interaction between collector species and the mineral surface. This takes place by a mixed potential mechanism involving separate electrochemical steps. The process that leads to a hydrophobic mineral surface is an anodic
