Corrigendum to “An attainable region approach for the recovery of iron and zinc from electric arc furnace dust [South Afr. J. Chem. Eng.](S1026918518300830)(10.1016/j.sajce.2018.12.002)

The authors regret that the names of Dr. Ralph Farai Muvhiiwa and Professor Ayo Samuel Afolabo (as highlighted above) were erroneously left out in the published version of the article. Dr. Ralph Farai Muvhiiwa developed and gave a detailed description of the G-H plots in the manuscript while Prof Ayo Samuel Afolabi worked on the experimental program and data analysis with the first author. The two were erroneously excluded from the submitted article after they left their respective institutions for greener pastures. Upon reflection and inquiry from both of them, I acknowledge that removing them from the manuscript's list of authors was an error in judgement. The authors would like to sincerely apologise for any inconveniences caused by this request to make things right. Sincerely Gwiranai Danha
