PURPOSE: A high-purity copper oxide is provided which is produced from etching wasted liquid without intermediate products and has seamless crystal phase. CONSTITUTION: A production process contains the following steps of: (1) a first step wherein a copper chloride wasted liquid is added to a ...
The most important compounds are the oxide and the sulfate, blue vitriol; the latter has wide use as an agricultural poison and as an algicide in water purification. Copper compounds such as Fehling’s solution are widely used in analytical chemistry in tests for sugar. High-purity copper (...
The trend of declining copper head grades is well established and unlikely to be reversed. Similarly, oxide ore bodies, which do not require concentrators and can be processed through less capital-intensive routes, are being exhausted. The mining industry has responded to these challenges by proces...
Microstructural analyses of the slag cakes identified metallic iron in the process of being chemically reduced from iron oxide. Taken together, the evidence from these sites provides a reasonable, though perhaps not definitive, argument for iron smelting. Slag adhering to the bloom may liquify and ...
This paper discusses the investigation and testing to better understand the effect of baking plated copper sub-assemblies before Oxide Alternative process. Previous documented work had discussed the benefits of baking electroplated copper before Sulfuric acid and Hydrogen Peroxide type micro-etches including...
Morphologic observation and function, reactive oxygen species (ROS) level, antioxidant indices, nitric oxide (NO) content, mitochondrial membrane potential (MMP), and apoptosis-related mRNA and protein levels were determined. These results indicated that excessive Cu could induce release of intracellular...
Photoelectrochemical water splitting is a promising solution for harnessing solar radiation for hydrogen production. Copper oxide semiconductors, particularly materials based on cuprous oxide, have attracted attention due to their abundant elemental availability and scalable synthesis methods. To improve the gen...
In the ore-dressing plant, the material received from the mine is crushed in several stages and finely ground to a size which ensures that copper minerals are liberated from the waste materials, organgue. In cases where the next step is leaching (most frequently in the case of oxide ores)...
Zn SOD with essential cellular components (Bruijn et al., 1998; Johnston et al., 2000; Cleveland and Rothstein, 2001) and this has been demonstrated with the copper chaperone for SOD (CCS) (Kato et al., 2001), nitric oxide synthase (NOS) and phosphorylated neurofilaments (Chou et al.,...
The present study examined the anticancer capabilities of Bacillus coagulans supernatant-produced copper oxide nanoparticles (BC-CuONPs) on MCF-7 and SKBR3 cancer cells. The X-ray diffraction, ultraviolet–visible spectroscopy, Fourier-transform infrared
