Using Murmansk Region, one of Russia's largest mining regions, as a case study, this paper examines the environmental safety challenges arising in the storage of mining and mineral processing waste (MMPW). It was found that MMPW causes environmental damage even after the deposit's exhaustion. While being stored, the MMPW composition experiences a major change in the process properties of

Dietary copper requirement of juvenile Russian sturgeon
To quantify the dietary copper (Cu) requirement of Russian sturgeon Acipenser gueldenstaedtii, copper sulfate (CuSO 4 ܫH 2 O) was added into the basal semipurified diet at seven levels 0, 1, 2, 4, 6, 8 and 16 mg Cu kg − 1 diet yielding the actual dietary values of 0.3, 1.5, 2.4, 4.4, 6.2, 8.3 and 16.1 mg Cu kg − 1 diet, respectively. Each diet was fed to sturgeon (11.84 ± 0.07 g) in

In the present study we discuss the value of multielement geochemistry as a tool for semiquantitative to quantitative bulk mineral characterization in geological and geometallurgical modeling of porphyry copper type deposits, with an emphasis on hydrothermal alteration associations, types and intensities.
Cuprite: The copper mineral cuprite information and pictures
Cuprite is named for the Latin cuprum, "copper" in allusion to its copper content.It can form as bright transparent red crystals, or as lustrous, submetallic opaque crystals. Even the opaque form will have slightly red edges and faint transparency upon backlighting.

Copper oxosulphates from fumaroles of Tolbachik volcano
The new mineral puninite, ideally Na 2 Cu 3 O(SO 4) 3, was found in sublimates of Glavnaya Tenoritovaya fumarole. The mineral is named in honor of the Russian crystallographer Yurii Olegovich Punin (1941–2014). Puninite is closely associated with lammeriteβ, tenorite, hematite and anhydrite. Puninite is emeraldgreen in colour.
Composition of Common Brass Alloys thebalance
Brass is a metal alloy that is always made with a combination of copper and zinc. By varying the amount of copper and zinc, brass can be made harder or softer. Other metals — such as aluminum, lead, and arsenic — may be used as alloying agents to improve machinability and corrosion resistance.
