Cupellation process is used in the metallurgy of: (AIPMT 2011)

Cupellation is a process used in metallurgy for refining of ores. In this process, the ores are treated under very high temperature with different methods in order to separate the noble metals from impurities of zinc, lead, copper, arsenic, antimony or bismuth. Therefore, the correct answer is option (b) silver. 23. Park’s process is used: (AIPMT 2011) (a) to extract silver using NaCN (b) to extract copper using CuFeS₂ (c) to extract silver from argentiferrous lead (d) to extract silver by forming amalgam Park’s process is carried out for the extraction of silver from argentiferrous lead
