چکیده
The use of waste rock as an aggregate in mining backfill is environmentally friendly and cost-saving. slurry flow property varies with the change aggregate, binder content, solid concentration, additives. a pipeline governed by its properties, which makes it crucial to study properties their effects. One example fly ash-waste mixed Jinchuan Nickel, China. Tests on slump, slump flow, mortar consistency, layering degree, bleeding rate are performed reveal effects ash addition properties. Those relations analyzed, two new indices derived (F1 F2) using principal component analysis method. Finally, application results show that F1 > 0 indicates nonhomogeneous flow; < F2 high-density paste flow.

Evaluation of the role of a cationic surfactant on the flow characteristics of fly ash slurry.
Transportation of fly ash is a major problem in its efficient disposal. The main problem associated with fly ash transportation is that the particles settle down sooner than desired. The primary objective of this research is that not only the fly ash particles should remain floated till it reaches the end but also settle down after that. In this investigation the role of a drag-reducing cationi...
متن کاملStabilization of acid generating waste rock with fly ash – immobilization of arsenic under alkaline conditions
A fly ash was used to increase pH and decrease arsenic leaching from an acidic mine waste. Both the amended system as well as the control system was leached with ultra pure water. pH in the control increased from 1.7 to 2.7 at the end of the experiment while the pH in the amended system decreased from 12.6 to 11.5. compared to the control the initial concentrations of arsenic decreased with alm...

متن کاملPhysicochemical Properties and Possible Applications of Waste Corncob Fly Ash from Biomass Gasification Industries of China
As a by-product generated from the processing of corn, the production in China of corncob (CC) is abundant, with up to 3.87 million tons per year. The biomass gasification industries make use of the CC residue as feedstock, but large volumes of generated corncob ash (CCA) requires daily disposal. In this study, CCA was characterized by laser particle size analyzer (LPSA), X-ray fluorescence (XR...
