During the mining, crushing, beneficiation and transportation of rich Mn ores, about 30% of the mined ores are converted into manganese ore fines with low Mn grade (Singh et al., 2011). In India, almost half of manganese ore resources are ferruginous in nature (Singh et al., 2011, Singh and Biswas, 2017).

Threedimensional block models are the most frequently used tool for estimating mineral resources and reserves within a mineral deposit. In open pit mining, the basis of mine design and the long term mining schedule is calculation of the ultimate pit limit. The ultimate pit limit is the pit with the highest profit value. Over the years, different algorithms have been developed that enable us ...

Since the particle size of the ore feed cannot be less than 100 mm, the design iron ore model diameter is 100 mm. According to the physical properties of the iron ore obtained by experiments, such as the porosity and coordination number, the diameter of the fraction used to fill the iron ore particles was determined to be 5 mm.

The dynamic path of the monthly timeseries of iron ore imports is affected by many factors, and the data generation process is difficult to reflect accurately in a timeseries model. To predict China's import tonnages of iron ore, in the present work, an EMDNARNNARIMA model based on the idea of decompositionintegration is proposed.
