The answer is impossible to accurately give. Just like ANY ore (gold, silver, zinc, niobium, copper, tin, etc) it all comes down to two things: 1) what is the grade assay of the ore? and 2) where is the mine located? Not all ore is created equall quantities of high-grade mineral ore deposits. 1.1.2 Development If the mineral ore exploration phase proves that there is a large enough mineral ore deposit, of sufficient grade, then the project proponent may begin to plan for the development of the mine.
Mine cost estimation may be done at many levels. At first it may be a simple "back of the envelope" estimation using similar operations to benchmark against. Later it may be decided to use an existing mine that the company owns and factor and compare costs against them.
A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface
Iron Ore Processing for the Blast Furnace (Courtesy of the National Steel Pellet Company) The following describes operations at the National Steel Pellet Company, an iron ore mining and processing facility located on the Mesabi Iron Range of Minnesota.
Grade Optimization: This stockpiling approach is used in situations where the mine delivers more ore than is required by the plant, thereby allowing the best grades to be processed directly while lower grades are stockpiled for a future date.
Reduce processing cost for gold and copper extraction Many existing gold refractory operations have low-grade stockpiles that are waiting to be processed at the end of the mine life. By adding Rapid Oxidative Leach (ROL) pre-treatment to an existing operation, it can become viable to process these low-grade stockpiles earlier, rather than processing them at the end of the mine life.
International iron ore prices too have gained 21 per cent, thus giving comfort that the domestic iron ore prices would either remain stable or move up. Currently, the landed cost of NMDC's ore at the steel plants of its clients is 20-30 per cent cheaper than that of international ore.
IN 1960, THE COST OF PRODUCING A LONG TON OF ORE FROM AN UNDERGROUND MINE IN THE MARQUETTE RANGE WAS $10.88, AS COMPARED TO $11.80 FOR THE GOGEBIC RANGE, AND $9.87 FOR THE MENOMINEE RANGE. DECLINE IN COSTS FROM 1959 WAS DUE TO CLOSING HIGHER-COST MINES AS DEMAND DECLINED (MINERALS YEARBOOK 1960, V. III, P.

Different percentages of iron content reflect both the natural variation in iron ore grades found in mine deposits and the degree of processing (if any) employed to upgrade the ore for a certain use. In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke required.

Taconite, the principal iron ore mined in the United States, has a low (20 percent to 30 percent) iron (Fe) content and is found in hard, fine-grained, banded iron formations. The main taconite iron ore deposits are located near Lake Superior in Minnesota (Mesabi
However, these mines became more and more expensive as shallow, high grade deposits became depleted and the cost of mining equipment, transportation, and regulations increased. For underground mines, once the site has been identified, a mine shaft is typically drilled down to the ore bed.
A rarely used process of mining material, In-Situ or solution mining is the process of pumping a solution into the ore body, which dissolves the ore and is then extracted by a second pump. This method is used most in mining uranium deposits, with the Beverey Uranium Mine in South Australia being the nations first operating In-Situ Uranium Mine.
Iron Ore Imports into China Below are the top 15 suppliers from which China imported the highest dollar value worth of iron ore during 2019. Within parenthesis is the percentage change in value for each supplying country. Australia: US$61 billion (up 69.5% from 2015)
The lowest grade mine was Evolution's Ernest Henry processing an average head grade of 0.56 g/t. The high-grade operations that do not report an AISC were AuStar Gold's (ASX:AUL) Morning Star mine with 10.26 g/t and Mandalay Resources' (TSE:MND) Costerfield mine with 5.00 g/t.
For example, if the ore is very high grade or carries a high price, then a higher cost method can be used. In order to minimize the mixing of ore and waste, highly selective extraction methods are available, but if ore and waste can be separated easily later (for example, by using magnets in the case of magnetite ), then a less-selective bulk mining method may be chosen.
