Recycling of sulfur slag
Thread Content
I understand that the sulfur slag produced in sulfur manufacturing can generally be used as a component in cement. I’m wondering if there are any other uses for it; please let me know!
Many uses: 1. After magnetic separation, iron ore concentrate can be produced; by controlling the process, the iron content in sulfuric acid slag can be increased, yielding significant benefits； 2. Advanced processing to produce iron red and magnetic iron – this yields good profits, but it’s more complex and requires larger investments ； 3. Producing cement is the least cost-effective ； 4、
The application of sulfur slag in cement production is not very clear; is the author referring to the red slag produced from the production of acid from pyrite? Sulfur slag is generally used in the production of acid from pyrite.
I’m referring to the waste residues generated in the production of sulfuric acid; those produced from the use of pyrite for acid production contain a high amount of iron, with Fe3O4 seeming to be the main component. This waste can be utilized in coal washing and flotation processes. I’ve looked up information on the waste residues from sulfur-based acid production, and it says that adding them to cement raw materials can help reduce costs. It seems like a good method.
Sulfur can be refined further, and it can also be used as a co-firing material in the production of acid from pyrite.
If the original poster provides the test results, it will be more helpful in clarifying things
There are no test reports available in this regard. We are in the trading business, and we mainly want to understand the basic knowledge in this field. Conducting tests costs money, so generally we don’t do such tests on our own; the company covers those expenses.
