Rhenium is a valuable rare metal that is primarily captured as a by-product during the processing of copper and molybdenum. Its complex capture pathway and low annual production (< 100 tons per year) mean that there is limited information about how current capture compares with the amounts of rhenium geologically present in mined …
Under the condition that the residual chlorine is guaranteed, the biofilm still thrives in drinking water distribution systems through secreting a large number of extracellular polymeric substances (EPS), in which protein components are the primary precursor of disinfection byproducts (DBPs), mostly in the form of combined amino acids.

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.

During copper (Cu) production, the concomitant arsenic (As) is generally dispersed into various As-bearing byproducts which need to be disposed separately. This work presents an integrated disposition method for the hazardous As by returning the As-bearing byproducts to the copper flash smelting process and solidifying As into …
The consumption of total oxidants was investigated because HOCl and HOBr are difficult to distinguish in terms of detection. In the absence of TAsp, the self-decay of oxidants (decomposition through XO 3 − and O 2 production) was greatly accelerated by CuO [18], given that the oxidants were almost entirely decomposed after 12 h of reaction …
What are the byproducts of producing copper through mining? By-products generated in the process are sulfur dioxide and slag. The sulfur dioxide is captured for use in earlier leaching processes.
