Bed-blending "Bed-blending" is a term used to describe systems whereby each reclaim slice includes as similar as possible an amount of material from all layers of material stacked. A mathematical model for bed-blending can be derived by considering a situation in which material is placed into a two-dimensional array of containers.

A serious problem faced by the metal mineral mining industry is the challenge to the sustainable development of resource mining due to the continuous decline of ore geological grade. In the case of producing concentrates of the same quality, compared with using only high-grade raw ore, ore blending is a way to slow down the decline of ore geological grade by …
Occasionally when working in Tableau, you will have to perform a function called data blending, which involves combining data from different sources. When blending data, you merge data from a secondary data source and display it alongside data from a primary data source in a view (i.e., a visualization).
ore quality is to produce ore of consistent grade (not only in iron, but also in phosphorus, silica, and alumina). Traditionally this is achieved by blending from intermediate stockpiles, but this imposes large handling and stock costs which would be avoided if the desired grade uniformity can be achieved with less rehandling of the ore.

fluctuation of delivered material is decreased. The entire process is called the blending operation in iron ore handling. Bed blending theory was firstly discussed by Gerstel in 1977 (Gerstel, 1977). Not far from that, Gy presented a new bed blending theory to suppress the continuous input variations for a steady output quality grade (Gy, 1981).
