有色金属冶炼过程中主金属价态变化规律

对传统矿物之重金属、轻金属、稀有金属、贵金属冶炼以及电子垃圾在金属提炼过程中主金属价态发生的变化规律进行了归纳整理,并绘制成图形。结果表明,轻金属和稀有金属的冶炼过程价态变化基本对应Z字形,相对不活泼的重金属冶炼过程的价态变化呈凹字形,贵金属的冶炼过程价态变化呈凸字形。我们认为,这些基本规律的存在,跟各元素的金属活泼性直接相关。以上规律的梳理,可以对开展城市矿产资源的循环再生新思路、新方法探索起到一定的助益和参考。 

Law of metal valence variation in the smelting processes of various nonferrous metals

This article summarized the changes in the valence state of the main metals in the metal refining process of heavy metals, light metals, rare metals, precious metal smelting, and electronic waste in traditional minerals, and drew them into graphs. The results showed that the valence changes basically corresponded to the zigzag shape during the smelting process of light metals and rare metals, they were concave during the smelting process of relatively inactive heavy metal, and convex during the smelting process of precious metals. We believed that the existence of these basic laws was directly related to the metallic activity of each element. The combing of the above rules could provide help and reference for us to explore new ideas and new methods for the recycling of urban mineral resources.
