Answer (1 of 2): As Joe Neumann observes, "It can depend on many factors." Whilst from a grade perspective, your ore falls within the generally accepted range, albeit at the lower end, it is the form that may present the biggest challenge. The feed to most smelters is a powdered concentrate and ...

Considering this, how do you calculate lower heating fuel value? Under this formula, the relationship between the lower heating value of a fuel and the higher heating value of that fuel is: LHV = HHV – 10.55(W + 9H) Where: LHV = lower heating value of fuel in Btu/lb, HHV = higher heating value of fuel in Btu/lb, W = Weight % of moisture in fuel, and H = Weight % of …

MINERAL ORE RESERVE Case 1. When all holes have positive values, let a, b and c, be the depth of ore in the three holes forming the prism; to find the average depth of the ore influenced by any given hole, use the formula: d = 4a + b + c/6. Then, as one proceeds from hole to hole, b and c should be substituted, thus: 4b + a + c/6 and 4c + a + b/6,
