Common misconceptions in crystallography and crystal optics. [PDF]
J Appl CrystallogrSix recurrent misconceptions in crystallography, some involving mineral and crystal optics, are analyzed and discussed. The explanation of these and similar misconceptions could serve as educational resources for teachers.Did you know that an X‐ray diffraction pattern is not a spectrum?

Arsenic content in the lead flotation concentrate in dependence on NaCN dosage [PDF]
Mining and Metallurgy Engineering Bor, 2013 Flotation properties of arsenopyrite are similar to the flotation properties of pyrite. Specifically, in the alkaline conditions (pH value of pulp 7-11) and in the presence of xanthates as collectors, arsenopyrite can easily pass into concentrate ...

Advances in the Separation of Pyrite and Arsenopyrite by Oxidative Flotation
Kuangchan zonghe liyong, 2023 This is an essay in the field of mineral processing engineering. Pyrite and arsenopyrite are common associated sulfides. Because their crystal structures and surface properties are very similar, their flotation separation has been an important research ...

CHEMICAL SPECIATION OF GOLD IN ARSENOPYRITE [PDF]
The Canadian Mineralogist, 2000 The speciation of Au in gold-bearing arsenopyrite (FeAsS) from four gold deposits (Olympiada, Sentachan, Sao Bento and Sheba) was determined by micro-X-ray absorption near-edge structure (XANES) on grains well characterized microscopically and by electron-microprobe and secondary-ion mass spectrometry analyses and images.

Journal of Materials Research and Technology, 2020 Ferric iron has a significant effect on the bioleaching of arsenopyrite, the most efficient way for pretreatment of arsenopyrite-bearing gold ores. Up to date, the differential effect of Fe(III) compounds on that process was rarely studied. Herein, FeCl3,

Carrier-microencapsulation using Al-catecholate complex to suppress arsenopyrite oxidation: Evaluation of the coating stability under simulated weathering conditions [PDF]
MATEC Web of Conferences, 2019 Arsenopyrite (FeAsS) is the most common primary arsenic-sulfide mineral in nature, and its oxidation causes the release of toxic arsenic (As). To mitigate these problems, carrier-microencapsulation (CME), a technique that passivates sulfide minerals by ...

Formation of surface protective coatings on arsenopyrite using Al-catecholate complex and its mode of inhibition of arsenopyrite oxidation [PDF]
MATEC Web of Conferences, 2019 Arsenopyrite is the most common arsenic-bearing sulfide mineral in nature. It is readily oxidized and releases toxic arsenic (As) into the environment when exposed to atmospheric conditions via anthropogenic activities like mining, mineral processing ...
