Thionocarbamates in Copper Slag Flotation
Thionocarbamates are the group of collectors that are mostly used for flotation of sulphide copper minerals, alone or in combination with xanthates depending on a mineralogical composition of the ore. Collectors are a group of reagents used in flotation for enhancing hydrophobicity of wanted minerals. They are organic compounds which are being adsorbed on surfaces of desired minerals, thus making them hydrophobic, reducing the stability of the hydrated layer separating the mineral from the air bubble to such extent that attachment of the particle to the bubble can be made, i.e., collectors reduce the induction time. Another purpose of collectors is to provide selectivity of minerals with similar floatability properties.

Unmanned Aerial Vehicles in Mine Closure/Rehabilitation Projects
Unmanned aerial vehicles (UAVs) are being used more frequently nowadays because of advancements in sensor and control technologies. They can use a range of single-band, multispectral, and hyperspectral sensors, including those that function in visible, infrared, and microwave spectrums. Their application in heritage and archaeological site mapping, transportation, civil engineering, agriculture, landscape mapping, wildlife conservation, infrastructure inspection, and search and rescue have been investigated in several studies.
