Companies like NTN who produce precision machinery use many grinding machines in their manufacturing processes. This machinery produces a lot of grinding swarf or industrial waste, most of which is dumped into landfills. Being an ISO14001-certified company, NTN thought that it was responsible for helping establish recycling …
This work presents a novel hydrometallurgical approach for recycling steel swarf and production of ferric chloride by selective separation of iron from heavy metals. Swarf containing 69% iron was leached with hydrochloric acid. A leachate containing 24.600 mg/L Fe with 150 mg/L Mn, 12 mg/L Ni and <1 mg/L Cr and Mo was obtained.
Swarf Management Swarf management Swarf (or filings, shavings, metal chips or turnings) are generated by grinding, drilling, turning, milling or cutting tools in the machining of metals and other elements. 2 …
The ferrous grinding swarf was obtained from the automobile industry in North America. Fig. 1(a) shows the image of the as-received ferrous grinding swarf. The relatively wide size distribution of the sample can be observed in the photo. It was agglomerated together to form a large size due to its moisture and oil residue.
Depending on the composition of the grinding sludge, it is possible to recycle up to 80% of the grinding sludge only by recycling the metallic swarf. This indicates the …
Grinding swarf is a hazardous waste generated in the manufacturing industry when making products out of iron and steel. Annually 10-12 million tons are generated worldwide, and these numbers are projected to grow with steel production and industrialization of developing countries. Waste management of grinding swarf is challenging because of …
This paper presents a brief review of the history of titanium smelting and the current trends in related research and development. Presently, both electrolytic and metallothermic reduction processes utilizing various feed materials such as titanium oxide are widely studied.
