T.5.1.14 Good practices of metallurgy of copper 

Module I: The main objective of this module is to describe the European regulation of the management, characterization and valorization of the waste generated in the copper industry. Examples of waste valorization in the Smelting Copper Plant of Huelva will be shown.   

Module II: The three main objectives of the course are the development of a computer-aided design (CAD), the use of computer-aided manufacturing (CAM) software to generate G-code that the CNC (Computer Numeric Control) machine can use, and the production of the copper component. Students will gain virtual practical experience with copper machining in this course. Some of the topics covered include copper properties, tooling requirements, fixturing techniques, setup procedures, program development, and tool path optimization. 

Module III: The aim of this module is to understand the development of the metallurgy of copper in Atlantic Copper. 

Module IV: The objectives of the module are: (1) Understand the metabolism of iron and/or sulfur oxidizing acidophilic bacteria, (2) Explain the implication of bacteria in the generation of AMD, (3) Recognize the possible applications of such bacteria in copper metallurgy, (4) To review the state of the art of the use of acidophilic bacteria in the mining industry: experiences in Chile and China, (4) To know and understand the experimental methodology prior to the use of acidophilic bacteria in the mining and metallurgical industries. 

Module I: The course is focused on analyzing the European regulation on waste and expose some real cases of waste valorization of smelting copper plant of Huelva. 

Module II: The course is focused on making a CAD Drawing, generating the G-code using CAM software and then manufacturing the part.  

Module III: Some of the processes of the metallurgy of copper carried out in Atlantic Copper will be explained. 

Module IV: This module intends to know alternative methods of low cost and low environmental risk in the mining and metallurgy of copper, based on the use of microorganisms typical of mining areas rich in metal sulfides.
