Novslag Grinding For Metal Recovery

  • Induction Melting of Titanium

    Induction Melting of Titanium

    Feb 05, 2021 The primary purpose of the research covered by this report was the development of a method for induction melting titanium in a water-cooled copper crucible. The results reported represent findings obtained during the melting of a minimum number of ingots; therefore, only tentative conclusions can be drawn regarding the effects on metal quality of many of the operating procedures.

    Jul 18, 2013 The purpose of this research is to develop a model for treatment of copper slag produced during copper alloying. Two copper slags were used, one from melting very pure metal to produce silicon brass (slag 1) and the other from remelting scrap to produce brass (slag 2). The model involves crushing, sizing and grinding followed by sieving and ...

    Mar 01, 2021 The obtained solid products were leached by water to recover the synthetized metal salts by leaching. Besides the temperature influence, the effect of co-grinding duration and impact of the carbonate on the recovery extent of Cr, V, and Mo was evaluated. Table 5 summarizes the best conditions for the recovery yield of these three metals.
