Weathered granite contains a high concentration of feldspar, quartz, and kaolin. However, while it becomes rich in clay due to strong physical weathering, the granite minerals that are not fully weathered are still very hard, which makes the grinding process more difficult and limits its use. This study proposes a multi-step process involving …

These include produced formation water (PFW), drilling fluid chemicals, oil-based drilling muds and cuttings, water-based drilling muds and cuttings, and of course oils including both crude oil from extraction processes and fuel/diesel oil …
This paper describes an environmentally friendly and efficient milling-assisted technology to produce soluble potassium from natural K-feldspar with the additive of calcium salts, and capture CO 2 via mineralization. The milling-assisted process could facilitate the extraction of potassium from K-feldspar under mild conditions (e.g. 30–40 …
Feldspar occurs in the pegmatite rocks and are associated with quartz and muscovite near the top of the granite (Fig. 1) (Pollet-Villard et al., 2017, Simmons et al., 2016, Swanson and Veal, 2012).The feldspar storage is approximately 10 billion tons worldwide, mainly occurring in North America, Europe, and East Asia (Zhang, …

Large quantities of solid waste are added to the environment in Ethiopia due to rapid growth of sugar industries. One such solid wastes that is generated in the sugar production chain is SCBA, produced during the use of sugarcane bagasse as fuel in boilers for energy co-generation. One ton of sugarcane bagasse may generate 25 kg of …
The effects of soda-lime waste glass, from the recovery of bottle glass cullet, in partial replacement of Na-feldspar for sanitary-ware ceramic production are discussed.
This article describes a novel CO2 mineralization approach using natural insoluble K-feldspar and phosphogypsum for the emission of CO2, reduction of phosphogypsum waste, and production of soluble potash. K-feldspar was activated with CaSO4 at high temperature and then mineralized with CO2 to extract potassium under hydrothermal …
