Scott Sturgis

Scott Sturgis is a Seattle, USA-based music producer, best known for his power noise/rhythmic noise project Converter. The harsh and distorted sounds of Converter were influenced by noise music and artists featured on the Ant-Zen record label. He has since released material on both Ant-Zen and its imprint label Hymen Records.

History

Sturgis was involved with electro-industrial band Pain Station when he began work on Converter as a side-project in March 1998. Sturgis has since been quoted as saying "Both projects are pretty equal in my eyes and neither one takes precedence over the other right now. Of course, if you ask me which project is more fun to work on, I'd tell you it's Converter." Up until Exit Ritual (made on a Roland MC-909), Sturgis used only an Ensoniq ASR-10 keyboard/sampler to produce music. Sturgis has also worked under the aliases DBS, Notime, and Lowness.

Converting (metallurgy)

Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. A now-uncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.

Converting in copper metallurgy

A mixture of copper and iron sulfides referred to as matte is treated in converters to oxidize iron in the first stage, and oxidize copper in the second stage. In the first stage oxygen enriched air is blown through the tuyeres to partially convert metal sulfides to oxides:

Since iron has greater affinity to oxygen, the produced copper oxide reacts with the remaining iron sulfide:

The bulk of the copper oxide is turned back into the form of sulfide. In order to separate the obtained iron oxide, flux (mainly silica) is added into the converter. Silica reacts with iron oxide to produce a light slag phase, which is poured off through the hood when the converter is tilted around the rotation axis:
