Roasting and calcination are distinct processes used for different types of ores. Sulphide ores are typically roasted to convert them into oxides, facilitating metal extraction, while carbonate ores undergo calcination to release carbon dioxide and produce metal oxides. Roasting carbonate ores can lead to undesirable reactions, potentially resulting in the formation of toxic gases and loss of valuable materials. Conversely, calcinating sulphide ores may not yield the desired metal oxides and can result in inefficient extraction processes.
