Development of an expert system for iron ore classification
The accurate classification of iron ores is one of the challenging tasks in the mining industry, and at the same time, it is essential for the future destination of the ores. The present study attempts to develop a machine-vision-based system, combining feature extraction, feature selection, and image classification, in order to predict the class of the iron ores. A total of 280 image features ...

Iron Ore Pelletizing Process: An Overview
The iron ore pelletizing process consists of three main steps: 1. Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing …

The tested granular material is copper ore of particle size 0–1.25 mm and relative moisture content 0.5–5%, fed to the installation at various rates. Higher moisture of input material is found to change the operation of the classifier. Computed correlation coefficients show increased content of fine particles in lower product of classification.

Classification of Ore Deposits
The genetic classification should ultimately determine the limits of ore deposition in each class by temperature and pressure. Each deposit should be considered as a problem in physical chemistry, and the solution of this problem, with the necessary geologic data, will suffice to fix the mode of formation of the deposit.

Truck Haulage - MiningInfo
Truck haulage is the most common form of materials transport in open pit mines. Trucks can be used to haul ore and waste out of the mine or they can be used to haul to an in-pit crusher where ore and/or waste can be crushed and then conveyed out of the mine.

Ore Minerals : What are Ore Minerals? - Geology Page
Ore Minerals. An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable ...

Classification of tungsten ores; Tungsten ores; Tungsten does not occur naturally in its pure metallic state; rather, it is found in several ores, but only two kinds of tungsten-bearing mineral rocks, called wolframite and scheelite, are mined commercially. Wolframite accounts for about 70% of the total tungsten resources in the world, and scheelite accounts for about 30%.

Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level ...

Ore - Wikipedia
Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.

Mineral Ore Deposits: Meaning, Origin and Types | Geology
In another common method of classification, ore minerals are divided into hypogene (also termed primary) deposits and supergene (also known as secondary) deposits. The secondary deposits are formed as alteration products of primary deposits through weathering and related processes. An ore deposit may be either of igneous or of sedimentary origin.
