El concentrado de plomo-plata que es materia de investigación tiene un contenido de plata de 210.7 oz/tc, 16.20% de plomo y 18.7 % manganeso, el cual es difícil comercializar. El objetivo de esta investigación consiste en minimizar el contenido de manganeso del concentrado de plomo-plata, por ser este elemento que diluye los contenidos de plomo y plata, perjudicando la comercialización del concentrado mencionado. El proceso de disminución de manganeso de un concentrado plomo-plata se puede adaptar a minerales con el mismo problema, alto contenido de manganeso (18.7%). Como subproducto de la lixiviación de manganeso se obtiene, una solución un sulfato de manganeso la cual mediante procesos se obtendrá sulfato de manganeso monohidratado. En la etapa de flotación se corrieron 4 pruebas iniciales que constan de tres etapas, la primera etapa fue a una lixiviación a pH=4, le segunda ...

The ore is complex and presents abundant content of sulphurs: pyrite, arsenopyrite and pyrrhotite, also in few proportion: chalcopyrite, sphalerite and probably sulfhosals that add: copper, silver, arsenic and antimony. Free gold is not appreciated in the obtained results, the major content of gold is in tails of flotation Cu-Ag, constituted by sulphurs of iron, as a non metallic residue prevails the quartz, coal and the insolubles, it is quite strong and naturally very acid, pH:5.3. It is possible to obtain a concentrate of flotation Cu-Ag, with As and Sb like pollutants and around 80% of the total gold stays in tails, to which we effect a direct cyanidation having variant like pH and granulometry, it has not been possible to leach more than 11 % of the gold contained in tails that gives 3.2 grams Au/TM, considering the current prices it has an approximate value 100 US $ Ton.
