ISO 12742:2007 specifies a flow-table method for the determination of the transportable moisture limit (TML) of copper, lead and zinc sulfide concentrates, which may liquefy during transport.
The moisture content of Mount Garnet Copper Concentrate forms sulphurous acid which is corrosive to the ship`s steel structure so that the cargo holds should have adequate coating. ... The test results for the respective copper concentrate showed that it could liquefy if the moisture content exceeds the TML range of 9.5% to 10.5% 6 so that it ...
The decrease in the solid moisture content causes the nearly dried particles to reach temperatures beyond the saturation temperature of water. In addition, the concentrate outlet temperature simulated by the model is 148.2°C, which is very close to the actual exit concentrate temperature of 148°C.
The temperature of the sample is then increased to 140 ... copper ore and pyritic waste 1 shown in Figure 3 have a history of spontaneous combustion without using preventive action. It should also …

Copper producers gain several cost-saving advantages by employing a dryer for copper concentrates prior to the smelter. By the time they are ready to be smelted, copper concentrates typically contain anywhere between 6-14% water. The different smelting technologies have varying requirements for moisture content.

The study of flash combustion of copper concentrates has been traditionally approached from the phenomenological perspective by describing the physicochemical transformation at the particle level. Few works have focused on analyzing and modeling the behavior of flames produced by a cloud of particles under equivalent flash smelting …
The influence of whey protein concentrate (WPC), feed moisture and temperature on the physicochemical properties of rice-based extrudates has been investigated. WPC (0.64–7.36 g/100 g rice) was extruded under 5 moisture (16.64–23.36 g/100 g) and 5 temperature (106.36–173.64 °C) established by a 3 2 central composite …
Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister …
temperature. From the suspended state hot particles are separated and molten slag and matte are deposited on the furnace hearth. ... smelting of copper concentrate with the Saint ... test runs 14 to 18 tons of concentrate per day, with a moisture content of 3 to 4 pet, were smelted in the furnace.

The slag layer is 0.5 m thick, while the copper matte layer is 0.2–1 m thick. Copper matte and slag are discharged intermittently from the furnace. The slag, with a copper content of 1–2%, is cleaned, quenched with water, and then discarded. The copper matte is transferred by a ladle to the P-S converter for converting.
