Summary:
The Sossego iron oxide–copper–gold deposit in the Carajás Mineral Province of Brazil.
The Sossego deposit is associated with a 10 km regional structural shear zone striking northeast to southeast and dipping steeply to the south. A series of copper gold deposits are associated with this structure including Sequerinho, Sossego, Jatobá, Serra Dourada and Cristalino deposits.
The Sossego deposit has been divided into 4 main zones, from west to east areas: Pista, Sequerinho, Baiano and Sossego Hill of which, the Sequeirinho deposit is the most important in terms of size.
Sequerinho consists of a single and continuous zone of mineralization with a strike length of approximately 2000 m with weaker mineralization extending another 1000 m to the west. This deposit is situated about 700 m west-southwest of Sossego Hill and out crops as a prominent hill with approximately 40 m of relief over the general landscape.
The sulphide deposit has a sigmoidal shape, trending west-northwest on the extremities of the deposit, and northeast in the central portion. The western extremity is referred to as the Pista sector and the eastern portion is called the Baiano sector. Mineralization generally occurs as a series of sub-parallel bodies with aggregate thicknesses ranging from 25 m to nearly 300 m. Dips are generally steeper on the extremities, ranging from 70°S to sub-vertical. In the central portion of the deposit dips are locally as shallow as 45° t ........
Summary:
Sossego mining complex is located at Carajás, State of Pará in Brazil and comprises two main open pits (Sossego and Sequerinho), processing facility to concentrate the ore, and satellites deposits (118, Cristalino, Bacaba and Mata II projects).
The copper ore is mined using the open-pit method. Standard truck and shovel open pit mining is developed on 16 m benches. Contract mining is used for prestripping and also for mining at the contact between oxide and sulfide materials. After drilling and blasting cable shovels and front end loaders are used for excavation and loading. The material is hauled mostly by 240 t trucks either to the waste dumps near the pit or to the primary crusher. Low grade ore (Cueq < 0.5%) is stockpiled near the crusher and north of the pit for later use. The material is crushed and transported by conveyor for 4 km to the concentrator.
