Studies on Pyrrhotite. I : Combustibility of Pyrrhotite
Studies on Pyrrhotite. I : Combustibility of Pyrrhotiteapplication/pdf In order to obtain a precise understanding of the combustibility of pyrrhotite, the roasting reaction rates and the relations between the roasting reactions and the roasting temperatures were investigated. It was found that pyrrhotite had a fairly low combustibility resulting from the low ignitibility, the slow reaction rate of oxide ...

Bullion production in imperial China and its significance for sulphide ore smelting world-wide [PDF]
, 2015 Gold and silver production was of major importance for almost all ancient societies but has been rarely studied archaeologically. Here we present a reconstruction of a previously undocumented technology used to recover gold, silver and lead at the site ...

Studies on Pyrrhotite. III : Sintering of Pyrrhotite Cinder
Studies on Pyrrhotite. III : Sintering of Pyrrhotite Cinderapplication/pdf The progress of sintering of pyrrhotite cinder during the process of roasting was studied by measuring the resistance of cinder to the penetration of a slender rod. The results showed that pyrrhotite cinder, in general, began to sinter at 250-350℃ with a very high resistance to the penetration of a rod.

Characteristics of a New Carbonaceous Chondrite, Metal-Rich-Lithology Found in the Carbonaceous Chondrite Breccia Aguas Zarcas [PDF]
The Aguas Zarcas meteorite fell in Costa Rica on 23 April 2019 at 21:07 local time, with a total mass of about 27 kg. Hundreds of fusion-crusted stones ranging from 0.1 to 1868 g were recovered (The Meteoritical Bulletin). The meteorite was classified as
