Preparation of very pure metals.
One highly recommended book on refining precious metals is "Refining Precious Metal Wastes" by C.M. Hoke. It provides detailed information on various refining techniques, processes, and equipment needed for refining gold, silver, platinum, and other precious metals. It is often considered a comprehensive guide for individuals and businesses involved in precious metal refining.
Metallurgy is the study of metals and their properties, as well as the process for extracting, refining, and shaping metals for various applications.
slag
Extraction of metals from its ores and formation of ores. Studying their properties, their alloys,refining of ores.
Chlorine is bubbled through molten dore, converting the metals into chlorides.
The metal is melted and remoulded!
Electrolysis... Some people say electro refining
Generally when we speak of precious metals we think of Platinum, Gold, and Silver. In a broader sense, however, the "precious metals" currently traded on the Precious Metals Exchanges includes not only those 3 metals but also palladium, iridium, rhodium, osmium, and ruthenium. Historically Aluminum was once considered a precious metal because of the difficulty of refining it to its pure form. Modern refining methods have caused a precipitous drop in its price since the 1800s to where it is now one of the cheapest metals.
When gold is refining, it is called smelting. Smelting involves heating the gold to a high temperature to separate it from impurities and other metals. The purified gold is then typically cast into bars or ingots for further processing.
A lab tech in smelting and refining of non-ferrous metals may be responsible for conducting chemical analyses on samples, monitoring process parameters, ensuring quality control of the final product, and collaborating with production personnel to troubleshoot any issues that arise during the process. They play a critical role in maintaining the efficiency and quality of the smelting and refining operations.
Lead is not an ore. Lead is a metal which is obtained by refining lead ore (or which may be a byproduct of the refinement of other metals).
The purpose of the refining process is to remove impurities and contaminants from raw materials or substances, such as petroleum, metals, or chemicals. This process helps to improve the quality, purity, and usefulness of the final product. Refining also aims to ensure compliance with industry standards and regulations.
