Other Barriers to Source Reduction - Production of chemical is a byproduct of the blasting process. Reducing the chemical would possibly mean a reduction in blasting and therefore a reduction in mining production. |

Other Barriers to Source Reduction - Chemical is a by-product of blasting activities. The amount produced is based on amount of blasting. A reduction can only occur if copper ore production is reduced. Variabilities in amount produced from year to year is most likely the result of ore/rock hardness in the mine pit. |
