ITP Mining: Energy and Environmental Profile of the U.S.
Flotation alone accounts for 65 percent of the total energy required per ton to process phosphate. The total energy required to both mine and process phosphate was 70,670 Btu per ton. Mining requires 98 percent of the total energy needed, while beneficiation uses the remaining two percent. Table 8-2.
Oil shale separation using a novel combined dry beneficiation process
The density of oil shale is around 2.35 g/cm 3, generally higher than that of coal; the principle of coal beneficiation, however, provides insights that are relevant to oil shale separation processes. Traditional water separation processes mainly include the jigging washing process and heavy medium separation.
