Opencast Mining

S.K. Chaulya, G.M. Prasad, in Sensing and Monitoring Technologies for Mines and Hazardous Areas, 2016 Abstract. Opencast mining operations involve huge quantities of overburden removal, dumping and backfilling in excavated areas. A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of the dump for minimum ground cover area and also ...

Agro-industrial wastes and their utilization using solid ...

2018-1-2 · Agricultural residues are rich in bioactive compounds. These residues can be used as an alternate source for the production of different products like biogas, biofuel, mushroom, and tempeh as the raw material in various researches and industries. The use of agro-industrial wastes as raw materials can help to reduce the production cost and also reduce the pollution load from the environment.

Chemical Verification of the EOR Mechanism by Using Low ...

2019-12-12 · Recently, a chemical mechanism for enhanced oil recovery by low salinity water flooding was suggested. The key step in the mechanism was a localized increase in the pH at the clay surface due to desorption of active cations, especially Ca2+, as the low saline injection water invaded the porous medium. An increase in pH will remove adsorbed acidic and basic material from the clay surface and ...

Polymer‐coated nanoparticles for enhanced oil recovery ...

2014-3-6 · INTRODUCTION. Energy consumption worldwide is expected to increase by 50% relative to current levels by the end of 2030. 1 This growth is unlikely to be met by renewable resources, and thus there is a strong and growing demand for oil as a predominant energy resource. Primary and secondary oil recovery methods typically produce only 15–30% of the original oil in place, depending on the ...

2021-6-25 · As one of the most complete archaic human fossils, the Harbin cranium provides critical evidence for studying the diversification of the Homo genus and the origin of Homo sapiens. However, the unsystematic recovery of this cranium and a long and confused history since the discovery impede its accurate dating. Here, we carried out a series of geochemical analyses, including non-destructive X ...

Actually, there is a growing interest in the biotechnological production of lactic acid by fermentation aiming to substitute fossil fuel routes. The development of an efficient method for its separation and purification from fermentation broth is very important to assure the economic viability of production. Due to its high reactivity and tendency to decompose at high temperatures, the study ...

Decline in Antarctic Ozone Depletion and Lower ...

2018-1-4 · The Antarctic ozone hole is healing slowly because levels of the man-made chemicals causing the hole have long lifetimes. We use Microwave Limb Sounder (MLS) satellite data to measure O 3 over Antarctica at the beginning of winter and then compare it to O 3 near the end of winter to calculate depletion. During this period, nearly all O 3 change is due to depletion.
