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.

Thus, the total specific energy for concentrating iron ore at the average ore grade (∼ 50% iron) from Thanatia (% iron) was considered as the sum of the energy for the orehandling process and the energy for concentration. In our model, the minerals for concentration are obtained from Earth's crust; surface mining is assumed.

Openpit mining is a surface mining operation whereby ore, or waste, is excavated from the surface of the land. In the process of digging the surface of the land, a deeper and deeper pit is formed until the mining operation ends. It is usually suitable to determine the final shape of the pit before the mining operation starts.
