Bornite, an important copper resource, is commonly found in copper mines but has received less attention compared to chalcopyrite. This paper summarizes research on bornite (bio)hydrometallurgy, including leaching behavior and possible surface substances during dissolution. Further studies on bornite bioleaching are needed due to its significance in processing complex ores.
(Bio)Hydrometallurgy is a common technology in processing copper sulfide minerals. With the decline in ore grades and depletion of easily mined deposits, some complex ores with relatively small reserves need to be taken seriously. Bornite is one of the most important copper resources (following chalcopyrite and chalcocite) and the commonly associates in copper mines. However, less attention has been paid to bornite compared to chalcopyrite, and there are hardly any review papers on bornite (bio)leaching. The main purpose of this paper is to summarize the research on bornite (bio)hydrometallurgy. Leaching and bioleaching behavior of bornite are summarized, including co-leach with other sulfide minerals. The intermediate products and possible surface substances during bornite dissolution are discussed.
