- Significance: The Sweetwater Gold Mine complex, which includes an ore concentration mill, represents one of the best examples of a small gold mining site in California. Furthermore, the Sweetwater Gold Mine is associated principally with patterns of serial gold mining activities over many decades in Mariposa County—the southernmost of California's Mother Lode counties.

Kiruna Iron Ore Mine, Sweden - Mining Technology | Mining

With an ore body 4km-long, 80m-thick and reaching a depth of 2km, LKAB's Kiruna is the world's largest, most modern underground iron ore mine located in northern Sweden. Since mining began at the iron ore operation more than 100 years ago, Luossavaara-Kiirunavaara AB (LKAB) produced over 950Mt of ore, yet only one-third of the original ore body has been extracted.

Chemical Reactions and Kinetics - Purdue University

The integrated form of this rate law would be written as follows. We are interested in the moment when the concentration of 14 C in the charcoal is half of its initial value. Substituting this relationship into the integrated form of the rate law gives the following equation. We now simplify this equation . and then solve for t.


Ore deposits are crustal concentrations of useful elements that can be exploited at a profit. Like all crustal rocks, they consist of minerals formed by geological processes. There are four basic geological requirements for any ore deposit to form (Figure 1): - i) a source for the ore components (metals and ligands);

Integrated Rate Laws | Chemistry for Majors

The integrated rate law for zero-order kinetics describes a linear plot of reactant concentration, [A] t, versus time, t, with a slope equal to the negative of the rate constant, −k. Following the mathematical approach of previous examples, the slope of the linear data plot (for decomposition on W) is estimated from the graph.

When several reactants are involved, increasing the concentration of one of them may not affect the rate of reaction if not enough of the other reactants is available.
