Where can I recycle waste tin in Shenzhen?

waste tin is also called recycled tin. Waste tin recycling refers to tin waste in life or tin metal waste in industrial production. Recycled tin is a technology derived from the metallurgical process of recycling tin waste materials. The waste materials in refining and recycling tin include three categories: iron waste, tin-containing alloy waste and hot tinning slag. Iron scrap is low in tin (.5% ~ 2%) and large in quantity. The amount of tinplate consumed worldwide reaches 18 million tons every year. There are many kinds of tin-bearing alloy wastes, such as Babbitt bearing alloy, fusible alloy, solder (the above three are collectively referred to as lead-tin alloy), tin-blue brass wastes, etc., which generally contain 2% ~ 5% or more of tin, and at the same time contain components with recycling value such as lead, copper, antimony and zinc. Hot tinning slag contains a high amount of tin, and the quantity is small. In general, tin is recovered from tinplate, lead-tin alloy, tin-blue brass and hot tinning slag in industry. Tin recovered from tin-containing waste is called recycled tin. It is different from primary tin produced directly from concentrate.

The recycling price of tin slag is generally 73-15/kg, which is divided into lead and (lead-free) environmental protection. The specific pricing depends on the fineness and composition of tin slag.
