Ore processing – Waihi Gold
Ore processing At the processing plant, gold and silver are extracted from the ore The processing plant alternates between treating ore from the Martha Mine open pit and from the Favona underground mine Ore processing consists of the following stages:A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver This process removes 93% of the gold and 70% of the silverThe Mining Process – Waihi GoldOn arrival at the processing plant gold and silver are extracted from the ore using conventional carboninpulp treatment methods Waste rock is used to construct an engineered earth embankment to contain the tailings A water treatment plant treats excess water prior to discharge Work within the open pit is currently focussed on the North WallMining – Waihi Gold
Excavating the rock – Waihi Gold
Ore and waste rock are mined by excavators loading onto trucks In the open pit the trucks take their loads to the primary crushers or to stockpiles In the underground mine the ore is taken to stockpiles at the processing plant, while waste rock is stockpiled for reuse as backfill once mined The first part of the mining process involves finding the minerals Exploration for gold and silver for modern mining in Waihi began in the 1970s and prospecting continued into the 1980s Diamond drills bored into the ground at an angle of 45° and collected core samples from various depths Approximately 13,000 metres of drilling was completedThe mining process – an overview for students – Waihi GoldWaihi Gold – OceanaGold Waihi Operation OceanaGold is proposing to extend the life of mining in Waihi through the development of Project Quattro OceanaGold announced Project Quattro on Waihi Gold – OceanaGold Waihi Operation
Assaying – analysis of ore samples – Waihi Gold
Throughout the extraction process at the Waihi Gold mill, samples of solution, solids and activated carbon are removed for analysis to determine the efficiency of the process The solids and the carbon samples are analysed by the fire assay technique for gold and aqua regia for silverApr 13, 2020 Waihi Gold operates both the Martha Mine open pit and the Correnso underground mines in Waihi Mining at Correnso completed in Q1/20; narrow vein mining to continue throughout the year Process plant shutdown for Q2/Q3 2020 and then restarted in Q4 2020 for batch processing of narrow vein ore; then shutdown until Q2 2021Major Mines Projects Waihi Mine3 g/t For this reason, the gold extraction process is largely a series of concentration steps As gold and silver usually occur together and have similar chemistry, these steps do not usually separate the gold and silver The ore used by the Waihi Gold Mining company contains, on average, 29 g/t gold Gold Mining in Waihi
