In this research study, we focus on the tree test results as well first-order kinetic model to evaluate flotation data propose a conceptual design of circuit for specific coal sample. Results from showed it was possible achieve product with ash content less than 10% 8% combustible recovery and indicated sample, obtain low – condition. Kinetic some streams had same constant, so could combine sim...

In this paper, an ecological and chemical safety assessment of using RDF (Refuse-derived fuel) is considered. It shown that production consumption wastes, including combustible unclaimed fractions secondary material resources from household solid waste, which have undergone preliminary sorting preparation, in terms grinding cleaning non-combustible inert materials, are used as raw materials for...

in this work, we developed a method which combined the processes of acid-leaching, ammonium jarosite precipitating and electro-depositing to recover copper and nickel from electroplating sludge. residual sludge from an electroplating plant located in qingdao was used for acid-leaching, and more than 95% of copper, nickel, zinc, chromium and iron were extracted from the sludge. after acid-leachi...

The use of combustible tobacco products (e.g., cigarettes, cigars, pipe, bidis, kreteks, and hookah) among adults remains widespread around the world. Unless dramatic progress is made diminishing the initiation and increasing cessation of combustible tobacco product use, a billion preventable deaths will occur in the 21st century [1]. These deaths will be accompanied by unimaginable human suffe...

Four reduced-height (5 m) BS 8414-1 façade flammability tests were conducted, three having mineral-filled aluminium composite material (ACM-A2) with polyisocyanurate (PIR) and phenolic (PF) foam stone wool (SW) insulation, the fourth polyethylene-filled ACM (ACM-PE) PIR insulation. Each was constructed from a commercial engineer’s design, built by practising installers. The ACM-PE/PIR burnt so ...
