Dec 15, 2020 Waste printed circuit boards (WPCBs) are a critical component of WEEE, made up 4–7% of the total mass of WEEE [4], [5]. WPCBs are composed of metal, polymer, ceramic and other substances [6], [7], [8]. WPCBs improper treatment causes water and soil pollution, which is harmful to human beings and the environment [9], [10].
Jan 01, 2021 The E-Waste contains several materials like Gold, Silver, Copper, Ironetc. Extraction of all these metals from the scrapped electrical and Electronic Products in an environment friendly manner is of utmost importance. Electro chemical, Pyrometallurgical, Hydrometallurgical and Bioleaching are the most efficient methods to extract metals.
The recovery of valuable metals from waste printed circuit boards (WPCBs) is crucial in order to harness their economic resources, and prevents potential environmental contamination. However, selective extraction of Cu and Zn, and the co-extraction of other metals as impurities at ambient temperature using selected lixiviants such as HCl, H2SO4, HNO3, trifluoromethanesulfonic acid (TFMS), NaOH
Feb 22, 2018 The toxicity of waste printed circuit boards (PCBs) to bacteria was considered as the major limitation in bioleaching of copper from PCBs. To reduce the toxicity of PCBs, copper extraction from PCBs was investigated using bacteria-free cultural supernatant from some metallurgical microbial consortium, whose predominant organisms were Leptospirillum ferriphilum and Sulfobacillus
Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.
The exhausted coffee waste (ECW) has shown to have selectivity for removing cations of heavy metals such as Cd 2+,Cu 2+,Cr 6+,Pb 2+,Ni 2+ y Zn 2+ (Oliveira et al., 2008;Utomo and Hunter
This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using. Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of
plating, wire drawing, copper polishing, paint manufacturing, wood preservative using and printing operations. Typical concentrations vary from several thousand mg/1 from plating bath waste to less than 1 ppm from copper cleaning operations [6]. Copper is

This type of stone masonry is perfect for perimeter walls, garden sheds, and other similar structures. The Pros and Cons of Rubble Masonry. Pros: Rubble masonry can withstand bad weather, many natural disasters, and rotting due to old age. Rubble masonry
Sep 18, 2020 This types of stone masonry use in the compound walls, warehouses, garage, small houses, etc. This types of masonry vary cheap. 3. Random Rubble Masonry: This types of stone masonry
Dec 21, 2018 Stone veneer: The advantage of this type of masonry is that it can be used for added decorative appeal, while also protecting the surfaces of both exterior and interior walls. Once the structural wall has been put up, a one-inch veneer is formed with flat stones that are mortared onto the surface and held in place with metal tabs.
Mar 23, 2017 Ashlar Masonry: It is the type of stone masonry in which finely dressed stones are laid in cement or lime mortar is known as ashlars masonry. In this masonry are the courses are of uniform height, all the joints are regular, thin and have uniform thickness. This type of masonry is much costly as it requires dressing of stones.
