Abstract

LA FORMACION DE CONTAMINANTES EN EL DRENAJE DE ROCAS DE DESECHO O RESIDUOS SE REDUCE O SE EVITA PONIENDO EN CONTACTO LAS ROCAS DE DESECHO O LOS RESIDUOS CON UN COMPUESTO DE AZUFRE ORGANICO O INORGANICO EN COMBINACION CON UN AGENTE NEUTRALIZANTE, UN AGENTE DE FIJACION O UN AGENTE NEUTRALIZANTE Y UN AGENTE DE FIJACION. CUANDO SE UTILIZA UN COMPUESTO DE AZUFRE ORGANICO O INORGANICO CON EL AGENTE NEUTRALIZANTE O EL AGENTE DE FIJACION, LA CANTIDAD DE AGENTE NEUTRALIZANTE Y/O LA CANTIDAD DEL AGENTE DE FIJACION REQUERIDA PARA REDUCIR O EVITAR LA FORMACION DE CONTAMINANTES EN EL DRENAJE DE ROCAS DE DESECHO O RESIDUOS SE REDUCE SUBSTANCIALMENTE. LA CANTIDAD DE COMPUESTO DE AZUFRE APLICADA A LAS ROCAS DE DESECHO O RESIDUOS PUEDE ESTAR ENTRE UN 1 Y UN 5% DEL PESO Y LA CANTIDAD DE AGENTE NEUTRALIZANTE Y/O DE AGENTE DE FIJACION APLICADA A LAS ROCAS DE DESECHO O RESIDUOS PUEDE ESTAR ENTRE 1 Y UN 5% DEL PESO, EN BASE AL PESO DE LAS ROCAS DE DESECHO O RESIDUOS. LOS COMPUESTOS DE AZUFRE ORGANICOS O INORGANICOS SON AQUELLOS QUE TIENEN UN GRUPO DE SULFIDRILO O UN GRUPO DE SULFIDRILO IONIZADO O UN COMPUESTO DE AZUFRE QUE SEA CAPAZ DE PRODUCIR UN GRUPO DE SULFIDRILO O UN GRUPO DE SULFIDRILO IONIZADO.
