During the extraction and refining of nickel, copper and cobalt from ores in the Sudbury area, one step involves blowing of air into molten sulfides at about 1200 oC. This step which is called converting, oxidizes and removes iron sulfides, thereby increasing the concentration of the valuable metal sulfides. However, unfortunately also some of the valuable metal sulfides(nickel, copper and cobalt sulfides) get oxidized and reports into the slag phase which consists of various metal oxides.

在从萨德伯里地区的矿石中提取和精炼镍、铜和钴的过程中，一个步骤是在大约1200摄氏度的温度下将空气吹入熔融的硫化物中。这一步骤被称为转化，氧化并除去铁硫化物，从而增加有价值的金属硫化物的浓度。然而，不幸的是，一些有价值的金属硫化物(镍、铜和钴硫化物)也被氧化，并报告进入由各种金属氧化物组成的炉渣相。
