The OAI-ORE data model addresses two issues: the assertion of identity for both aggregations and their constituents, and the definition of a mechanism for the assertion of metadata for either the aggregation or its constituents.
Minerals Engineering 21(3), 5 9] an approach was described which enabled the specific energy of tumbling mills such as Autogenous (AG), Semi-autogenous (SAG) and ball mills to be estimated from laboratory-derived ore characterisation data.
In this study, a dynamic simulator combining ore characteristic physical data, process operating parameters and mineralogical properties is developed for the Oulu Mining School OMSS) mini-pilot scale mineral beneficiation plant.
In essence, it's as if the ore of our data-driven lives were being mined, refined and sold to the highest bidder, usually without our knowledge — by companies that most people rarely even know exist.
The London-listed miner is accused of violating forest-protection laws and the rights of tribal groups, but has said it will not abandon the project, which was expected to yield 78m tonnes of the aluminium-bearing ore.3PAR, a data-storage firm, was courted for a takeover by both Hewlett-Packard (HP) and Dell.
But given the labour involved in isolating a new element from tons of ores or of combing the data from a particle accelerator for the decay patterns that signal a new element, I wonder if it's not a touch of parental pride and privilege that keeps us mired in tradition.
We used USGS data on ore grades as well as on the structure of the mining industry in order to calculate gross ore while taking the occurrence of coupled production (more than one metal extracted from the same ore, e.g. lead and zinc as by-products of nickel mining) into account.
A design module has been developed for integrating slope stability analysis into the data management, ore reserve and pit optimisation processes of an open pit mine.
Another PCA was performed on the chemical data of ore, mill tailings, and biogenic solids listed in Table 2.
Based on the above work, a bauxite deposit in a longwall mining panel was modelled by scattered grade data from ores sampled on the entry wall.
The data on iron ore reserves, iron and steel productions and consumptions have been used in the models.
