the historical archaeology of ore milling ideaseach mill is analyzed through documentary and archaeological sources in order to understand how different forms of technology were implemented and modified to most effectively treat ores over time. locally, this process of technological adaptation was influenced by changing environmental knowledge.heap leach mining's breakthrough technology miningaug , · this would result in a dramatic expansion of the technology as ~80% of total ore types are sulfide in nature. heap leaching, at first sight, seems to be a relatively simple technology, but is inmining technology in the nineteenth century onemining technology consists of the tools, methods, and knowledge used to locate, extract, and process mineral and metal deposits in the earth. the methods used to locate ore bodies range from ontheground reconnaissance by prospectors to remote sensing techniques such as satellite imagery.grasberg open pit copper mine mining technologythe ore undergoes primary crushing at the mine, before being delivered by ore passes to the mill complex for further crushing, grinding and flotation. grasbergs milling and concentrating complex is the largest in the world, with four crushers and two giant semiautogenous grinding (sag) units processing a daily average of 240,t of ore.conventional mining uranium producers of americaintroductionunderground mininguranium ore millingregulatory and environmentalafter uranium ore is removed from the ground, it must be processed to extract the contained uranium. this process, milling, involves a sequence of physical and chemical treatment steps to extract the uranium from the native rock. the final product of milling is yellowcake or u3o8, which is the commercial product s by uranium producers to nuclear utility customers. during the peak u.s. uranium production period of the early 80s, a total of 26 uranium mills were operating, and the u.s. was the worlds leaflake graphite ore processing technologyoct 22, · when the steel rod works on the grinding mill, the steel rod contacts the mineral as surfacetosurface contact, so the coarse mineral can be grounded firstly, and the largescale graphite ore
