TGA and its derivatives are utilised as depressant agents in flotation procedures for separating beneficial metals from ores in mining functions. TGA derivatives can be a safer alternative to the more standard sodium sulfhydrate (NaSH), specially in mining environments.
Combustion during TG Investigation is identifiable by unique traces made inside the TGA thermograms created. One particular fascinating example occurs with samples of as-produced unpurified carbon nanotubes that have a large amount of metallic catalyst existing. As a consequence of combustion, a TGA trace can deviate from the traditional form of a very well-behaved perform. This phenomenon occurs from a rapid temperature modify.
