Ausenco has been involved in Barricks gold processing operations at the Goldstrike Mine for nearly a decade. Goldstrike is Barricks largest and most productive mining operation, with gold production of more than 40 million ounces since 1987 It is located on the Carlin Trend, approximately 40 km north-west of Elko, Nevada, USA. Mar 20, 2016 Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two waysdirectly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.

Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never 100% efficient, nor is it possible to reclaim all ... metal ores (1% copper, 1g/ton gold, 0.5% nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009).
