assessment that the Gold Processing plant is designed and will be operated in a manner which maximises energy efficiency and minimises greenhouse gas emissions as far as practicable. 1 Greenhouse gas emissions at the Gidji Gold Processing Plant. 2 Greenhouse gas emissions produced offsite in the generation of electricity.
The Albemarle Kemerton Plant emissions are comparable to the Tianqi Plant, although for most sources tend to be slightly higher. It is noted however, that due to the Plant being at conceptual (rather than detailed) design phase National Pollutant Inventory emission factors were used to calculate combustion emissions for the Plant.

can be treated in an acid plant. Weak gases, such as those from reverberatory furnaces and fugitive emissions, must be treated by alternate means. b Strong Sulfur Dioxide Emissions Acid plants (figure 8-2) convert the sulfur di-oxide in emissions to sulfuric acid (H 2 SO 4). Other conversions, including to gypsum, elemental sul-fur, and liquid SO 2
At Gold Coast Farms, we understand the importance of sustainability. We generate our power on-site with a natural gas-fueled cogeneration plant. This reduces our carbon footprint, controls costs, upgrades our energy infrastructure, and reduces emissions. A heat recovery system converts waste heat for various plant processing needs.
