Re: Fw: Ferrotitanium production using induction furnaces

	

	

	History:	

This message has been replied to and forwarded.

Conrad, 

 

I have reviewed numerous sources in regard to the term 

"electrometallurgical."  Most refer in some way to the the use of
electric 

and electrolytic processes. I believe the term is primarily meant to 

include electric or electrolytic processes that bring about the
reduction 

of metallic compounds (e.g. electric arc furnaces, electrolytic cells)
or 

the purification of the metals through 

electrorefining/electrodeposition.   I do not consider induction melting


to be an "electrometallurgical" process. 

 

Regards,

 

Joe Gambogi

Subject: Fw: Ferrotitanium production using induction furnaces 

Hello Joseph, 

I am following up on a voice message I left you a few minutes ago.  I am


a rulewriter developing the area source NESHAP for ferroalloys 

production.  Our basis of applicability determination for this rule is 

mostly based on the SIC code 3313.  Ferrotitanium is one of the 

ferroalloys listed under SIC 3313. 

However, Global Titanium, a ferrotitanium producer, informed us that its


process in FeTi production does not involve "electrometallurgical" 

process, and therefore should not be in SIC 3313.  I am seeking your 

opinion and expertise on this.  Could you please respond to my inquiry 

upon your return?   Thanks. 

P.S.  I also sent a similar inquiry to you colleague, Lisa Corathers.  I


am copying her on my inquiry to you.
