It is also known by its mineralogic name, tincalconite.
Summary: Kinetic parameters of tincalconite during thermal decomposition were explored with TGA data.
In this study, thermal decomposition related kinetic parameters for tincalconite were analyzed with TGA data and by means of Coats-Redfern [11] and Suzuki methods [12].
For studying the dehydration kinetics of tincalconite from thermogravimetric data, tincalconite particle sizes between 0.
The major peak value around 149 C is due to the first dehydration of tincalconite and the second peak value around 700 C is due to the second dehydration and subsequent boiling of the sample.
According to the results, the dehydration of tincalconite probably occurs in two steps as given below:Region I; mass loss: %21, temperature range: 190-215 C equationPartial loss of water from hydrated minerals is represented in this step.
Both steps are attributed to the dehydration of tincalconite.
This result is expectablebecause the dehydration of tincalconite is an endothermic reaction.
Hence, the concentrate was mainly formed from tincalconite crystals.
