Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·Here we show experimentally that the exsolution of chalcopyrite CuFeS2 lamellae from a bornite Cu5FeS4 digenite Cu9S5 solid solution bdss is a back reaction which occurred during low temperature annealing 150 °C following initial replacement of parent chalcopyrite by bdss at 300 °C The back reaction is rapid days and its
1 ·The Boltcrusher is a Legendary Thundercall Greathammer that scales off of and requires investment in both the Thundercall and Heavy Weapons stats It is a large Great hammer with a drill at one end of it with various pipes connected all over The cutting edge of Ignition Union technology the Boltcrusher was devised by Ignition Deepdelvers in order to assist in Depths
·Copper sulfides are widespread in both hypogene and supergene Cu deposits worldwide and are considered profitable Cu ores because of their high Cu content at ∼67 80 wt% Cu Vaughan and Craig 1978 Anilite Cu S digenite Cu S djurleite Cu S and chalcocite Cu 2 S are the Cu rich members of a group of minerals that range in composition
·La dignite se trouve dans la zone de transition d oxydation supergène de dpôts primaires de sulfure à l interface entre les zones de saprolite suprieure et infrieure C est rarement un minral important des gisements de cuivre car il est le plus souvent remplac par la chalcocite plus haut dans le profil de dgradation et il est un produit mineur de
This indicates that iron is essential for stability of digenite Synthetic digenite with the composition of Cu Fe S has the cell edge of × 5 Å The apparent space group of digenite Fm3m is considered to be a result of complex domain textures on

·Low and high digenite has been studied by X ray diffraction at room temperature and at temperatures up to 500 °C For the experiments the Debye Scherrer technique was used with buffered sulfur partial pressure at all temperatures The crystal structures of high digenite have been determined at 200 °C 300 °C 400 °C and 500 °C
·Copper sulphides chalcocite Cu2S djurleite Cu31S16 anilite Cu7S4 / digenite Cu9S5 and covellite CuS are the major ore minerals and are associated with quartz hematite and very minor uraninite
·Digenite is a copper sulfide of essentially secondary origin It comes from the alteration of chalcocite chalcopyrite and bornite and systematically accompanies secondary covellite in the oxidation and cemantation zones of copper deposits Primary digenite is much rarer known in basic intrusions and pegmatites

Here we combined nanoscale chemical and structural analysis to identify the mineral digenite 4Cu2S·CuS in Chang e 5 lunar soil This is the first report of digenite in a lunar sample
·Here we combined nanoscale chemical and structural analysis to identify the mineral digenite 4Cu 2 S·CuS in Chang e 5 lunar soil This is the first report of digenite in a lunar sample The surface correlated digenite phase is undifferentiated in distribution and compositionally distinct from its hosts suggesting that it originated from
·Digenite is an important ore of copper although it is not very well known even by mineral collectors The reasons for this lack of appreciation for digenite could be due to the fact that it does not generally form good crystals lacks brilliant colors and is easily confused with other copper sulfides But as is the case for any mineral that
·The copper grade is only % and copper mainly exists in the form of secondary copper sulphides digenite covellite enargite First the primary jaw crusher PEX 150 × 250 mm and secondary jaw crusher XPC 60 × 100 mm were sequentially applied to comminute the Zijinshan copper ore
·Digenite is the dominating intermediate solid solution of the Cu S system with a broad phase field covering a compositional range approximately from the Cu 2 S stoichiometry up to at pct S According to the review of Chakrabarti and Laughlin [] digenite melts congruently at 1403 K ± 2 K 1130 °C ± 2 °C and is stable over a wide temperature range down to 345 K
