This method uses the approach to control potential leaching bismuth sulfide ore with chlorine gas selectivity, and resistance to leaching of impurities. A large amount of iron ions in the process of circulation and regeneration of ferric iron are avoided, the product quality is improved, and the filtration and washing performance of the slag are also improved. The basic reaction of the leaching process is: The selective leaching of chlorine gas has a high selectivity, but the chlorine gas consumption is relatively large. Some elemental sulfur will be oxidized by chlorine gas to form sulfate. Chlorine gas pollution and corrosion problems are also serious, and the equipment needs to be sealed. From an economic analysis, there is no obvious superiority over leaching with ferric chloride. The process flow for chlorine selective leaching is shown in Figure 1.

Here are some key features and benefits of using a PU system for shoe soles:
1. Cushioning: PU provides excellent cushioning and shock absorption properties, making it ideal for footwear that requires high levels of comfort and impact protection.
2. Lightweight: PU is a lightweight material, which helps reduce the overall weight of the shoe, making it more comfortable to wear and reducing fatigue during extended use.
3. Flexibility: PU offers good flexibility, allowing the shoe sole to bend and flex with the natural movement of the foot. This enhances comfort and prevents stiffness or discomfort during walking or running.
4. Durability: PU is highly durable and resistant to wear and tear, making it suitable for long-lasting shoe soles. It can withstand repeated use and exposure to various environmental conditions without losing its structural integrity.
5. Slip resistance: PU can be formulated with specific additives to enhance its slip resistance properties, providing better traction and grip on different surfaces. This is especially important for safety footwear or shoes used in slippery conditions.
6. Design versatility: PU can be molded into various shapes and designs, allowing for greater design flexibility and customization options for shoe soles. This enables manufacturers to create unique and visually appealing footwear.
7. Water resistance: PU can be made water-resistant or waterproof, which helps protect the shoe sole and the foot from moisture, rain, or other wet conditions.
Overall, a PU system for shoe soles offers a combination of comfort, durability, flexibility, and design versatility, making it a popular choice for footwear manufacturers and consumers alike.
