Os britadores móveis também podem ser chamados de plantas de britagem móveis, britadores móveis, etc. É um produto inevitável da tecnologia de britagem de alta tecnologia na nova era, e suas principais características são que pode ser operado de forma móvel, pode andar livremente e é mais conveniente para transições, garantindo que o equipamento Enquanto a produção é segura, o trabalho o processo é mais confiável.
Secondly for the provenance of Bayan Obo Group this paper believes detrital zircons with age of Ga and Ga were from Guyang Xi Ulanbulang and Zhuozi area; the Khondalite Belt provided detrital zircons with age of Ga; zircons with age of Ga might come from granitic rocks in Miyun Area
The Bayan Obo ore deposit in the Inner Mongolia autonomous region of China 109°58′E 41°48′N is situated on the northern margin of the North China Craton and adjacent to the Central Asian Orogenic Belt Fig 1 A The geology of this ore district is shown in Fig 1 The crystalline basement of the area is the Archaean Wutai Group which
The unique giant rare earth element REE deposit at Bayan Obo northern China is the world s largest REE deposit It is geologically complex and its genesis is still debated
： There are four ore forming heat events in Bayan Obo deposit 1 Proterozofic period; 2 LateProterozoic period; 3 Caledonian period; 4 Hercynian period;these events are determinated with radioisotope methods of whole rock and minerals
Detrital zircon ages of Jianshan Formation H4 quartz sandstone of Bayan Obo Group record two major tectonic magmatic events in the northern margin of the North Chian Craton NCC One Group of age concentrates in the Late Archean—Early Paleoproterozoic 2379 2596 Ma and the other in the medium Paleoproterozoic 1761 1946 Ma
In the Bayan Obo deposit REE ores are hosted in dolomites including coarse grained and fine grained varieties and many carbonatite dikes ferroan magnesian and calcic have been identified All of the dolomites and carbonatite dikes appear to be broadly coeval and possess similar geochemical characteristics
Regardless of their exact petrogenesis carbonatites are key REE economic resources with the world s largest REE deposit being the Bayan Obo carbonatite complex located in northern China Fig 1; Le Bas et al 1992; Yuan et al 1992; Le Bas et al 1997 The Bayan Obo ore body is hosted in a dolomitic marble with an unclear origin even after 90 years of
The Bayan Obo REE Nb Fe deposit which reserves the current largest REE resources globally also hosts over 70% of China s Nb resources Unlike many world class carbonatite related Nb deposits Morro dos Seis Lagos and Araxá Brazil with igneous or

The Bayan Obo deposit in the Inner Mongolia North China Craton is the largest rare earth element REE resource in the world The deposit is hosted in Mesoproterozoic sediments of the Bayan Obo Group the lithological sequence of which has been divided into seventeen units H 1 H 17 The REE mineralization is mainly concentrated in the H8 dolomite
