Tungsten's unique properties and the excellent cutting and wear resistance properties of its
carbides have made it a strategic commodity of high importance globally. Cemented …

The scraped and end-of-life tungsten carbide materials demand innovative recycling
methods to recover valuable refractory and strategic metals like tungsten, cobalt, nickel etc …

Hard-metal sector, strategic for the industrial economies, is suffering from the reduced
availability and price volatility of its main feedstock: critical W and Co. In 2021, a 73.5 kt W …

Wet milling was fundamentally investigated as a process for dissolution of Co from WC–Co
hard metal scrap in this study. The development of a relatively fast and low acid …

Tungsten carbide-cobalt (WC-Co) hard metal scraps release toxic heavy metals into
groundwater when they are buried underground after industrial use. Recovering abundant …

Cemented tungsten carbide material has been widely used in the hard metal industry for the
manufacture of cutting tools, drilling tools, mining and machining tools and high wear …

Recycling of hardmetal scrap is strategic for critical raw materials recovery. Available
recycling processes are polluting and have a large carbon footprint. Attempts to exploit …

Electrochemical methods for the recycling of tungsten carbide (WC-10Co) resources suffer
from passivation in the acidic medium caused by WO3 and also in NaOH electrolytes, due to …

This study conducted an analysis of the carbothermal reduction of oxidized WC/Co
hardmetal scrap with solid carbon under an argon and hydrogen gas atmosphere. The …

Scraped or end-of-life WC-Co bonded makes it an attractive resource. The conventional
technologies to recover these metals entail energy-intensive pre-treatment steps, followed …
