An Integrated system for alluvial gold leaching-recovery was design to leach gold from alluvial ore as alternative to mercury and cyanide leaching. NaClO is obtained by NaCl 1 % in-situ electrolysis at pH 2 and used as leachate solution. Gold leaching optimization is achieved using a rotary drum reactor fed with the leaching solution, the process takes 6 hours and 95 % of gold recovery is obtained, the remnant gold from the alluvial ore is treated in an stationary reactor with NaClO 200 ppm at pH 2; reaching 99.6 % recovery of the total alluvial gold. This leaching-recovery alluvial system has the potential to replaced mercury and cyanide leaching process.
