Abstract: Carry on to some mineral of vanadium in Hunan indoor leaching to experiment,make sure the mineral's stone after prepare the processing,leaching a rate greatly for exaltation,leaching a time to also shorten,made sure to leach a rate to leach a time,temperature at the same time,the liquid is solid than,prepare to handle the temperature,prepare to handle time etc.relate to,experimenting the result make known:The mineral's stone is after prepare the processing and add to helpful-preparation leaching a rate from originally 50% raises to 87% or so,leaching a time to also shorten to 15 hours from original 20 hours
