Froth floatation is an important process used in the mining industry for separating minerals from each other. The separation process is based on rendering a selected mineral hydrophobic using an appropriate hydrophobizing reagent (collector), so that it can selectively attach onto the surfaces of a rising stream of air bubbles. Thus, controlling the hydrophobicity of the minerals to be separate...

the study was undertaken with the objectives to: (1) study the present status of plastic waste management and the existing phnom penh household willingness and their influence factors to segregate plastics for recycling and reuse (plastics & non plastics); (2) study how other cities encouraged and obtained the participation of their population in plastics recycling and reuse and (3) recommend w...

With the increasing output of new energy vehicles, higher requirements are put forward for automotive plastics. On basis accurately understanding advantages and applicable conditions various plastic materials, according to relevant standards, it is great significance development vehicle manufacturing industry design apply them vehicles. Taking bio-plastics carbon fiber reinforced plastics as ex...

Although thermal recovery of waste plastics is widely practiced in many European countries, reliable information on the amount of waste plastics in the feed of waste-to-energy plants is rare. In most cases the amount of plastics present in commingled waste, such as municipal solid waste, commercial, or industrial waste, is estimated based on a few waste sorting campaigns, which are of limited s...

Various approaches have been adopted to address this including preparation of solid dispersions and solid solutions. Hot-melt extrusion is an efficient technology for producing solid molecular dispersions with considerable advantages over solvent-based processes such as spray drying and co-precipitation. Hot-melt extrusion has been demonstrated to provide sustained, modified, and targeted drug ...

it has been proven that polyolefins specially low density polyethylene (ldpe), are resistant against degradation and microorganism attacks; thus, one of the most important properties of industrial plastics, is their environmental biodegradability. since plastics are being widely used in agriculture, horticulture and packaging, meeting this requirement becomes increasingly dificult (specially in...
