    Oct 09, 2020 The process is used to purify the silver containing lead as impurity. Impure metal is heated in a boat shaped bone ash shallow crucible, called cupel . Air is blown over the metal when lead present in the silver is oxidized to PbO (litharge) and is carried by the current of air while pure shining mass of silver is left behind

    Data extraction makes it possible to consolidate, process, and refine data so that it can be stored in a centralized location in order to be transformed. These locations may be on-site, cloud-based, or a hybrid of the two. Data extraction is the first step in both ETL (extract, transform, load) and ELT (extract, load, transform) processes
