acid leaching
Introduction
The process of leaching is widely used in the mining industry as a method of mineral extraction. This involves the process of dissolving valuable minerals from ore, by using a chemical leaching agent. Leaching has become increasingly popular because it is a cost-effective and environ......
Defects and Countermeasures of Large Forgings: Inclusions and Harmful Trace Elements
Defects of Large Forgings and Countermeasures
Large forgings usually refer to complex and large-scale forgings that weigh more than 10 tons and are difficult to process and inspect due to their large size, complex shape, high strength and low toughness. They are mainly used in petrochemical, powe......
Ways to Exclude and Reduce Non-metallic Inclusions
Removal and Reduction of Nonmetallic Inclusions
Nonmetallic (NM) inclusions, which are mostly oxides, sulfides, silicates, nitrides and carbon particles, are a major cause of surface defects and cracking of metallic products. These inclusions may be found in a variety of commercial aluminium prod......
Properties of metal-related compounds in casting
The Properties of Compounds Related to Metals during Casting
Casting is the process of pouring molten metals into a mold that has been shaped with a negative impression of the desired part that is to be produced. The mold can be formed with a variety of materials, such as sand and metal, and the ......
Zinc smelting
Extraction of Zinc
Zinc is an essential trace element involved in the proper functioning of numerous enzymes in humans, animals, and plants. It is a bluish-white metallic element of relatively low melting and boiling points. Thus, it can be extracted from ores containing zinc sulfide through a pr......

Non-Metallic Impurities in Metals
Metals are naturally occurring materials that have many important uses in everyday life such as manufacturing, construction, jewelry and even currency. Because of their diverse applications, metals are highly sought after and come in a variety of forms, including......
Sulfurization
Successful Use of SO2 (Sulfur Dioxide) in Wastewater Treatment
Sulfur dioxide (SO2) is commonly used as a treatment agent for controlling engineering and environmental problems in wastewater treatment systems. It is both a powerful oxidant and a reducing agent, and it can provide efficient treat......
Continuous casting slab defects
内容
Continuous casting is a major process used in the production of steel. An important measure of the quality of the final product is the presence or absence of casting defects. The purpose of this report is to identify and evaluate the most common defects found in continuous casting and how they......
