What is the main difference between tailings and lump ore in acid production?
Thread Content
Does anyone know: 1. What are the main differences in using tailings, lump ore, or mixed ore to produce acid? 2. To what extent does the ratio of tailings to lump ore in acid production using mixed ore affect acid production?
The main difference in producing acid using tailings, lump ore, or mixed ore lies, of course, in the raw materials used; the sulfur content need not necessarily differ and can be controlled. The tailings have a fine particle size, and the roasting intensity of the roasting furnace is low; as a result, the furnace required to produce the same amount of ore is much smaller. Then, the dust collection process using tailings as raw material incurs a high load, as there is a lot of dust. Using tailings in combination with lump ore requires careful consideration of the furnace’s and dust collection system’s capacity; proper control of dust collection should not cause any harm to the final acid production process.
