THE WAIPORI GOLDFIELD: A Brief History by David Still The route to the diggings. In 1861 the shortest route from Dunedin to the diggings at Gabriel's Gully was via West Taieri (Outram) and the Maungatua Mountain into the Upper Waipori valley, across the river and along the leading ridge before dropping down to Gabriel's Gully and Wetherston's.

253 +r = r0 S [H]a [A]b [C]c exp{Ea/(R T)} M (1) S is the effective mineral contact surface. The rate r0 is given in units of mol·s1·m2 or equivalent units. Knowledge of the above parameters a, b, c and (r0 S) for U mineral(s) and interfering sulphidic minerals ( pyrite) and organic matter is most important in optimizing the leach chemistry for a given deposit (

hydraulic properties of the aquifers, overburden and interburden. This data has indied a representative hydraulic conductivity for the Hunter River alluvium of about 8 m/day, and for the Saddlers Creek alluvium of about m/day. The hydraulic conductivity values for the coal seams

dewatering in the CID aquifer. This suggests good hydraulic connection between the alluvium and CID aquifers. Well efficiencies and hydraulic parameters such as hydraulic conductivity (K) and specific yield (Sy) for the CID aquifer were calculated from different monitoring bores. The average K and Sy for the CID are 25 m/d and 1x102 respectively.

Hydraulic Mining was a gold recovery method that was used during many of the gold rushes around the world during the 1800's. It was used extensively in California's Mother Lode county during the famous gold rush there. One of the problems that the early California gold miners faced with basic placer mining was the amount of manual labor that was required to process the gravels.

Jul 25, 2016 · Hydraulic mining also referred to as hydraulicking was developed in California at around 1850 for excavating soft underground deposits. In Hydraulic mining a high pressure jet of water is used to excavate and wash the gravel. Gold is then recovered by cleaning the bedrock. Hydraulic mining is efficiently used to mine placer deposits of gold ...
