Sticht was the developer of the first successful purely pyritic smelting in the world. He also helped increase copper production in Kyshtym, Russia, through the use of pyritic smelting. His successful dealing with pyritic ores marked him out as a great metallurgist. Gold is associated with silicic, kaolinitic, and pyritic alteration of greenschist-grade felsic metavolcanics. These bacteria can accelerate pyritic oxidation by 10 times. The Morgan Trail is a brownish-black to olive-black fissile siliceous pyritic shale. Copper production, using pyritic smelting, eventually reached 25,000,000 pounds a year. In warm climates it is possible to leave pyritic ore out in the rain. The Blocher consists of brownish-black to grayish-black, slightly calcareous pyritic shale. Near the ore horizons the shale is pyritic. The Clegg Creek is a brownish black pyritic shale that is rich in organic matter.
