Mining in open pits is mostly done with large powerful shovels and trucks. Shovels at taconite mines are used to dig surface overburden as well as iron ore and waste rock.Flow sheet is a typical representation of general processes used in a given plant to obtain the end product most conveniently. For the same end product using similar ores the operating conditions may vary from place to place however the general flow diagram remains the same. A generalized flow diagram for concentrating magnetite ore is ...6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Run-of-mine sulphide ore is delivered to the crusher dump pocket from the mine by 290 tonne rear-dump-haul trucks. Sulphide ROM ore is delivered to the crusher dump pocket from the mine. The crushing circuit is designed to process up to 148,000 t/d of ROM ore to a crush size of 80% passing (P80 value) of 159 mm size.Price to Net Asset Value (P/NAV) P/NAV is the most important mining valuation metric, period. Net asset value is the net present value (NPV) or discounted cash flow (DCF) value of all the future cash flow.

roasting the ore or concentrate to burn off the carbon. All of these techniques are relatively expensive however, so the economic cut-off gold grade for refractory ores is somewhat higher than non-refractory ores. The mining industry uses a rule of thumb of 80% gold recovery to define the transition from a refractory to a non-
