Where are the compounds of formula (i), where R and R each independently C1 - C6 C20 alkyl, aryl - C20, alquenilo C2 C7 aralquil C20 and C20, all being optionally substituted, preferably alcoxicarbonil N - S - (ethyl, propyl, butyl and Pentyl, Hexyl) dithiocarbamate, N - (ethoxy propoxy, Pentoxi, Butoxy carbonyl, or hexoxi) S - N - alkyl dithiocarbamate, aliloxicarbonil - S - (alkyl,Aryl or Allyl) dithiocarbamate -, - S - (n ariloxicarbonil Allyl, alkyl or aryl) dithiocarbamate, Butoxycarbonyl N - N - S - N - butyl dithiocarbamate -, N - butyl dithiocarbamate Ethoxycarbonyl s, N - (Butoxy ethoxy carbonyl, Aloxi or S - phenyl) dithiocarbamate, N - S - phenoxycarbonyl Allyl dithiocarbamate, N - (ethoxy propoxy or carb, Butoxy) Onil - S - etilditiocarbamato and propoxicarbonil - S - (N - butyl, propyl or Pentyl, Hexyl) dithiocarbamate.The Method involves the reaction of an alkyl or aryl Mercaptan Formula R1 SH, or with a ariloxi alkoxy carbonyl isothiocyanate formula (iii). The composition also includes a Second Collector Collector Selected xanthates, xantogen formats, thiophosphate, thioureas and Dithiocarbamates.The composition comprises a foaming agent (Collector (C6, C8 alkanol alcohol, glycol, polyglycol, Pine Oil and acid cresilico) and carbamate compounds. A Slurry of ore containing cu, ni, MO, Pb, Zn, au, AG, PT and PD are interspersed with the collector composition to form a foam, Paste containing 10% to 60% by weight of solids
