The global mining giant Vale, Brazil announced that Caracas S11D iron ore project located in the southern state of Pará is the first environmental permit has been issued by the Brazilian Environment and Renewable Natural Resources Authority.
S11D Vale iron ore industry in the history of the largest projects the company to achieve productivity growth and to maintain iron ore production, cost and quality in the global market leading main lever.
The project is located south of the Carajás region of Pará state, mining and processing plant construction is estimated capital expenditure of $ 8.039 billion, designed annual production capacity of 90 million tons, the average iron grade of 66.48% and low impurity content, is expected in 2016 to put into production. Investment in logistics infrastructure of the project is estimated at $ 11.4 billion, including the construction of the railway and Pontada Madeira port terminal in Caracas, a year after the completion of these facilities will be able to handle 230 million tons of iron ore.
According to the the target long-term sustainable to create the the value of, CVRD focus on the development of to environmental protection of the technology solutions, in order to more efficiently utilization of natural resources and reduce emissions of pollutants. Trucking mining concept using conventional truck system will be composed of excavators and mobile shredders replace mined iron ore will be shipped to the conveyor and then transported to the concentrator.
The use of natural moisture and processing of iron ore (dry process) is to reduce the environmental impact of another technology, which does not produce tailings, due to loss of fine mineral aggregate in the traditional process is retained in the final product, so that the ore maximize use.
Therefore, once the S11D mine and processing plant put into operation, water and fuel consumption will be reduced by 93% and 77%, 50% reduction in greenhouse gas emissions compared to traditional methods, the dry process each year will reduce the power consumption of 18 000 MW, which do may reduce the interference on the local environment.
