“…Our systematic mineralogical investigations of its ores over the last few years revealed a remarkable assemblage of rare minerals, most of which are Tl-sulfosalts. Among them, three minerals are completely new for the science: vorontsovite, ferrovorontsovite (Kasatkin et al 2018a) and tsygankoite (Kasatkin et al 2018b). Herein we describe gladkovskyite, the fourth new Tl-sulfosalt from this deposit.…”

Gladkovskyite (IMA2018-098), MnTlAs 3 S 6 , is a new sulfosalt from the Vorontsovskoe gold deposit, Sverdlovsk Oblast', Northern Urals, Russia. The new mineral occurs in limestone breccias cemented by abundant realgar, orpiment, baryte and pyrite, as well as minor clinochlore, fluorapatite, quartz and talc. Gladkovskyite forms long-prismatic crystals and grains up to 0.2 mm; it has dark cherry-red color and red streak. It is transparent with adamantine luster. The Vickers microhardness is 94 kg/mm 2. The new mineral is brittle, with uneven fracture; neither cleavage nor parting was observed. The density calculated based on the empirical formula is 4.356 g/cm 3. In reflected light, gladkovskyite is grayish-white, strongly anisotropic with rotation tints varying from light-grey to brown. Its pleochroism is moderate, from orange-red to dark-red, and bireflectance is very weak, ∆R = 0.58 % (589 nm). The empirical formula of gladkovskyite is Mn 1.01 Tl 0.99 Pb 0.01 As 2.86 Sb 0.13 S 6.00 (based on 11 atoms pfu). Prominent features in the Raman spectrum include bands of Mn-S and AsS stretching vibrations as well as numerous low-frequency bands related to phonons. Gladkovskyite is trigonal, R31c, a = 9.6392(2), c = 6.4560(15) Å, V = 519.49(12) Å 3 and Z = 2. The seven strongest powder X-ray diffraction lines are [d obs , Å (I, %) (hkl) ]: 5.11 (80) (101), 4.83 (70) (110), 3.49 (50) (201), 3.23 (30) (002), 2.86 (100) (-2-11, 211), 2.68 (30) (112), 2.55 (60) (301, 202). The crystal structure of gladkovskyite was refined from the single-crystal X-ray diffraction data to R = 0.0178 for 679 observed reflections with I obs > 3σ(I). It contains infinite chains of face-sharing MnS 6 octahedra, TlS 9 polyhedra and pyramidal AsS 3 groups; the structure belongs to the group of seldom occurring cyclic sulfosalts. The new mineral honors Russian geologist Boris Aleksandrovich Gladkovsky who discovered the Vorontsovskoe gold deposit.

“…In the Khokhoy ore field, a diverse spectrum of thallium minerals is attested. This fact makes closer to Carlin-type gold deposits in the West of the USA [1][2][3][4][5], Alshar epithermal Au-As-Hg-Tl deposit in Macedonia [40,41], Vorontsovskoe deposit in the Urals, Russia [7][8][9]42] etc. The main difference between the Khokhoy gold ore field and these deposits at this stage of research is the absence of As and Hg minerals-realgar, auripigment, cinnabar.…”

Typomorphic features of supergene gold in karst cavities were studied in the recently discovered Au–Te–Sb–Tl deposit within the Khokhoy gold ore field of the Aldan-Stanovoy auriferous province (Aldan shield, East Russia). Two morphological types of supergene gold, massive and porous, are recognized there. The first type is represented by gold crystals and irregular mass, with the fineness ranging from 835 to 1000‰. They are closely associated with goethite, siderite, unnamed Fe, Te, and Tl carbonates, Tl tellurites/tellurates and antimonates, as well as avicennite with a Te impurity. The second type is represented by mustard gold of two types with different internal structure: microporous and dendritic. The supergene gold is characterized by persistently high fineness. Along with Ag, it invariably contains Hg (up to 5.78 wt%) and Bi, and, rarely, Pb, Cu, and Fe. The supergene gold is chemically homogeneous, and its particles are all marked by high fineness, without any rims or margins. The obtained characteristics made it possible to prove the existence of two genetic types of supergene gold. Mustard microporous gold is the result of the decomposition of the associated minerals—goethite, Tl oxides, tellurium, Fe, Mn and Tl carbonates and antimonates, containing microinclusions of gold. Massive gold and dendrites are newly formed. The decomposition, remobilization, and reprecipitation of residual gold nanoparticles and their aggregation led to the formation of dendrites, and with further crystal growth and filling of pores, to gold of massive morphology. In terms of morphology, internal structure, fineness, and trace element composition, supergene gold of the Khokhoy gold ore field is comparable to gold from the Kuranakh deposit (Russia) and the Carlin-type gold deposits. It also is similar to spungy and mustard gold from Au–Te and Au–Sb deposits, weathering crusts, and placers. Its main characteristic feature is a close paragenesis with Tl minerals.

“…El anterior sistema fue propuesto por la limitada capacidad del cianuro para mantener la plata en solución en presencia de Sb o As, por lo que el proceso de cianuración se vuelve más lento, a pesar de encontrarse en un medio acuoso y alcalino. [13][14][15][16][17][18][19][20] Por lo anterior el objetivo del presente estudio es caracterizar mineralógicamente un concentrado de plomo, el cual es el producto final del proceso de beneficio de un mineral, para identificar si existe la presencia de sulfosales, debido a que se ha reportado que los procesos convencionales no han sido efectivos para llevar a cabo la disolución de metales preciosos contenidos en minerales complejos.

La caracterización mineralógica de un concentrado de plomo del distrito minero de Zimapán, Hidalgo, México, se realizó con la finalidad de identificar la presencia de sulfuros ternarios cuya prevalencia en el subproducto se atribuye a su naturaleza compleja. Estas especies minerales contienen una importante concentración de plata cuya extracción representa un importante valor agregado para el concentrado y su estudio abre pauta al desarrollo de nuevos procesos de lixiviación para la posterior recuperación del metal precioso. Para el proceso de caracterización se utilizó la combinación de varias técnicas analíticas como: Microscopia Óptica de Polarización (MOP), Microscopía Electrónica de Barrido (MEB) con espectrómetro de dispersión de energía (EDS) y Difracción de rayos X (DRX). Los resultados del análisis químico-granulométrico confirmaron la presencia de plata en una concentración promedio de 3.6 kg., y determinaron que la mayor distribución de plata en el concentrado se encuentra en el conjunto de partículas acotadas Los resultados de la caracterización fueron complementados por cada una de las técnicas antes mencionadas y reportaron una mineralización argentífera, constituida principalmente por sulfosales de Ag como la tetraedrita, freibergita (Ag4.2As0.12Cu5.82Fe1.56S13Sb3.88Zn0.42), polibasita (Ag3.1As0.203CuS22Sb3.793), y en menor medida argentita (Ag2S), también se observó la presencia de metales base asociados en forma de sulfuros. La matriz de la muestra mineral corresponde a la galena (PbS).
