Discussion on the classification of smelting sectors
Thread Content
I think the non-ferrous metal exchange area can be classified as follows: Heavy metal smelting, light metal smelting, rare and precious metal smelting, ferrous metal exchange area, steel smelting, manganese chromium metallurgy, hydrometallurgy exchange area, hydrometallurgical theory and new technology, structure of continuous leaching kettle, non-ferrous metal hydrometallurgy, precious metal hydrometallurgy, rare metal hydrometallurgy, biometallurgy technology, hydrometallurgy pollution control and safety and energy-saving technology. I don’t know if you have any good opinions? ?
It's too finely divided, and it feels like it can be divided into two pieces. One is non-ferrous metal and the other is ferrous metal.
If it is detailed, it will make it easier for everyone to find it! It can also improve efficiency
When you encounter a post with good reviews, you need to rate it.
It can be divided into colored and black, and colored can be divided into heavy, light, rare and expensive.
