Here we provide a detailed study of the shape transformation dynamics as a function of a range of different process parameters, such as photon energy and photon flux. For the first time, we provide direct evidence that the photochemical synthesis of silver nanoprisms from spherical seed nanoparticles proceeds via a lightactivated twodimensional coalescence mechanism.

The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

Instructions for Silver Refining using Acid
The process is quite simple. the silver is dissolved in nitric acid; the acid with the dissolved silver is poured into another container. Undissolvable contaminants are left behind. the silver is turned back into silver by adding silver precipitant crystals (SPC) to the acid. the acid is poured off and neutralized.

Epic World History: Silver in the Americas
In 1700, New Spain's silver production hovered around 5 million pesos annually. By the 1780s, the figure had quadrupled. As early as 1600, silver ore, bullion, and coins constituted some 80 percent of New Spain's exports, making it far and away the largest and most important industry in Spain's wealthiest and most important colony.
