The worldwide demand for recycled cobalt and tungsten has increased due to the recent trend of battery materials and the European Union’s regulations on recycled materials. Lianyou uses secondary materials to recycle tungsten and cobalt intermediates using clean technology, achieving an annual output of more than 3,000 tons of tungsten oxide.

Solving supply chain cycle dilemmas

Taiwan’s industry has seen an increasing demand for imports of cobalt, tungsten and their compounds. Especially in the context of the booming electric vehicle market, the demand for battery materials is growing exponentially. EU regulations are also promoting the rapid industry developments toward a closed-looped circular supply chain.

Closed cycle of tungsten and cobalt metals

Lianyou Metals uses secondary tungsten carbide as raw materials, through patented recycling processes to recycle them into raw materials to produce tungsten intermediates, supplying downstream tungsten ,producers with critical raw material. At the same time, Lianyou Resources also produces other precious metals from tungsten carbide ,alloys, for example cobalt, tantalum, niobium. The company’s main products include sodium tungstate, calcium tungstate, etc., while also producing cobalt carbonate, cobalt sulfate and other related products.

New technologies drive new production models

Lianyou Metals has developed a newly patented cemented carbide recycling technology to replace the traditional energy-inefficient rotary furnace method. At the same time, waste heat recovery systems and water-saving processes have been introduced into the production process as the company actively moves toward net-zero carbon emissions and resource recycling.

▪ Lianyou Metals has become one of the top five sodium tungstate suppliers in the world with 100% of its tungsten products originating from recycled resources.

▪ Produces at least 3,000 tons of tungsten oxide each year, estimated to save the Earth from excavating over 3 million tons of deposits annually.

▪ Reduces CO2 emissions by 64% compared to traditional tungsten mining (tungsten and cobalt combined) [1].
