Abstract
En una primera instancia, se presenta un primer metodo para aislar oro de materiales auriferos. El metodo comprende varios pasos. En el primer paso, se anade HX y acido a los materiales auriferos para formar una primera solucion de oro disuelto. El HX es un haluro de hidrogeno. En el segundo paso, se anade una base a la primera solucion de oro disuelto para formar una segunda solucion de oro disuelto. En el tercer paso, se anade ciclodextrina a la segunda solucion de oro disuelto para formar un precipitado en la segunda solucion de oro disuelto. En el cuarto paso, se aisla el precipitado de la segunda solucion de oro disuelto. El precipitado comprende oro en la forma de un complejo de oro-ciclodextrina. En una segunda instancia, se presenta un segundo metodo para aislar oro de materiales auriferos. El metodo comprende varios pasos. El primer paso es generar una solucion que comprenda hipobromito de sodio o hipobromito de potasio. El segundo paso es anadir la solucion al material aurifero para formar una primera solucion de oro di suelto. El tercer paso es anadir ciclodextrina a la primera solucion de oro disuelto para formar un precipitado en la solucion de oro disuelto. El cuarto paso es aislar el precipitado de la primera solucion de oro disuelto. El precipitado comprende un complejo de oro -ciclodextrina. En una tercera instancia, se detalla el tercer metodo para aislar oro de materiales auriferos. El metodo comprende varios pasos. El primer paso es anadir una
