1. What is fine metallurgy? Fine metallurgy, also known as material metallurgy, is an interdisciplinary science that studies the processes and theories involved in directly producing fine metallurgical products, fine chemical products, and fine material products from metallic ores or recycled resources. It is a cutting-edge field that arises from the intersection of metallurgy, chemical engineering, powder technology, and materials processing. 2. What does fine metallurgy include? Fine metallurgy includes unit processes in fine metallurgy, metallurgy of chemical materials, metallurgy of high-purity materials, metallurgy of ultra-fine and nanomaterials, metallurgy of functional materials, and metallurgy of composite materials. 3. What is the difference from traditional metallurgy? Fine metallurgy: It involves the production of high-value fine products directly from mineral raw materials or recycled resources, without going through the stage of producing pure metals. Features: Short process, low consumption, high efficiency. Traditional metallurgy: The production of high-value specialty products requires two stages – first, pure metal ingots are obtained through extractive metallurgical methods, and then high-value specialty products are created using fine chemical processes or powder and material technologies. Features: The process route is long, consumption is high, and costs are high. 4. A process flow diagram for preparing ultra-fine gold powder from coarse gold powder as a typical example.
