| Abstract | A copper removal process was carried out in a Pb-Cu alloy through sulfur powder injection of three different sizes (79.23, 202.83 and 597.15 μm) by a top submerged lance with nitrogen as carrying gas. The higher copper removal as CuS$_{2}$ was obtained for the sulfur powder size of 79.23 μm, while the lowest copper removal efficiency was attained for the coarse particle size of 597.15 μm. The copper removal was explained according with a relationship between the residence and melting time. The sizes of 202.83 and 597.15 μm presented a longer residence time that promotes the sulfur coalescence and it is lost by burning. An injection-cooling trial was developed and a decoppering fraction of 0.29 with a sulfur efficiency of 72.98% in average was obtained for the fine size. The injection-cooling process represents an attractive route for secondary lead producers in the copper removal from molten lead. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
