oxidizing roasting造句

New technology development for gold ore oxidizing roasting

The Change of hot strength of iron ore pellets during oxidizing roasting and reduction was researched.

Extraction technology of vanadium from the sodium roasting, the non-salt oxidizing roasting, the stone coal soaking by acid (alkali) and its evolvement process were introduced.

Experimental results have shown that oxidizing roasting is an effective pretreatment method for this carbonaceous gold ore.

A critical temperature was found, at which the strength of pellets is severely dropped during the oxidizing roasting.

The appropriate conditions that the enriched Ge-bearing lignite in Lincang brown into coal ash with oxidizing roasting method was studied.
