The annual capital of tin slag reduction technology is tens of billions
The Chinese government has recently announced plans to invest over one hundred billion Chinese yuan into zinc dross reduction technology, technology which promises to revolutionize the metal smelting industry. This technology converts zinc dross, an industrial by-product, into high-grade zinc with......
slag
The importance of slag in modern life
Slag, or industrial waste, is a ubiquitous product of the modern age, produced from melting metals, burning coal, and other industrial processes. As industrial production has increased, so too has the amount of slag generated all over the world. While it can b......
Recovery of InGeGa by Full Extraction
Introduction
Indium, gallium and germanium are major by-products of zinc smelting, and their recovery and reuse in the zinc production industry are important parts of environmental protection, resource conservation and sustainability. Among these three elements, indium, gallium and germanium, due......
Aluminum ingots for steelmaking deoxidation and ferroalloying
Steel and iron alloys are important materials in a variety of industries, including aerospace, automotive, and construction. Aluminum dross, which is a by-product of aluminum smelting, can be used as a deoxidizing agent for steel and iron alloys. Aluminum dross is a powdery material that is made u......
Gold extraction by metallurgical by-products
Introduction
Metallurgical by-products recovery, particularly gold recovery, is becoming increasingly important. This is due to the wide variety of sources of gold. For example, gold can be produced from precious metal scrap or old jewelry, or it can be obtained from ore deposits. In both cases, ......
Silver electrolytic refining
Silver Electrolytic Refining
Silver is a commonly used metal in industries such as jewelry making, coins and photography. It is also a valuable commodity since it is scarce and in high demand. As a result, it is usually necessary to refine high quality silver from raw ore sources or recycled mate......
Vertical tank zinc smelting residue treatment
Steel slag processing
Steel slag is a byproduct of the steel production process. It is produced from residual iron ore, metallurgical coke, and fluorinated slag. Steel slags are generated during the smelting process, when large amounts of iron ore and coke are heated at high temperatures. The sla......
Flat tank zinc smelting
Zinc refining is the process of making zinc metal from various raw sources, including hazardous waste such as dust, scrap and residues, to create a usable alloy. This process is widely used in a variety of industries, including automotive, electronics, and construction.
The first step in zinc ref......
Lead pyrolysis
Lead Refining by Fire Method
Refining lead by fire dates back to ancient times and the method is the oldest form of lead production. Refining lead by fire involves melting lead ore and then separating the lead metal away from its impurities. This process cannot be done without the proper material......
