摘要
Abstract
In this paper,the influence of morphological characterization of oxide copper on copper leaching rate was carried out by using chemical mineral processing.The acid leaching experiment of the two different oxide coppers was studied by using sulfuric acid as the lixiviant.The influencing factors were investigated such as the dosage of lixiviant,leaching time and height of raw ore,etc.Meanwhile,the morphological characterization of copper in raw ores and tailings was researched through by means of scanning electron microscope(SEM),and the results showed that coppers were in the form of thin films covered on gangue minerals and granules in sample A and B,respectively.The acid leaching experimental results showed that sample A had a much higher copper leaching rate than the sample B.It might be attributed to the much larger specific surface area of sample A,leading to a more contact with sulfuric acid and thus a stronger chemical reaction.关键词
