prospecting model for Pbzinc (Zn) ore based on geological background of the metallogenic belt, basic characteristics of Pb–Zn deposits, and the conditions controlling Pb–Zn ore. Wu et al. (2011) established the metallogenic model of molybdenum (Mo) deposits on the basis of deposit geology, geochemistry, and isotope geochronology data. Gong
A number of case studies have been undertaken of implicit modelling in iron ore deposits. Stratigraphic surfaces of bedded, folded and faulted iron ore deposits have been modelled in various deposits by Leapfrog Geo, GOCAD (with SKUA) and Vulcan Integrated Stratigraphic Modelling. Leapfrog Mining was used to model iron grade shells at particular cutoff grades. The modelled surfaces are of a high .
Development of the underpinning ore deposit model requires integration of multilayer datasets, generated at a range of scales (both spatial and temporal), using a variety of techniques. Also required is a keen understanding of diverse but interrelated ore forming processes:

Hydrothermal Ore Deposits. The Pivehzhan iron deposit is located at about 80km southwest of Mashhad, NE Iran. It occur within the Devonian carbonates as lenticular and massive bodies, as well as veinlets .
Surface mining removes ore deposits that are close to the surface, and subsurface mining removes minerals that are deep underground. While mineral use is very important to us, there are also many environmental impacts, such as erosion, air and water pollution, land destruction and .
A total of 80 different geometric models of the Doris Hinge deposit were created. One model was created using the traditional modeling method (Figure 1), which is referred to as the "traditional" or "reference" model. Implicit modeling generated 79 geometric models in four separate stages, which are referred to as "implicit" models

The genesis of Earth's largest rare earth element (REE) deposit, Bayan Obo (China), has been intensely debated, in particular whether the host dolomite marble is of sedimentary or igneous origin. The protracted (Mesoproterozoic to Paleozoic) and intricate (magmatic to metasomatic) geological processes complicate geochemical interpretations.

Surface Mining. Most suitable for large ore bodies and for low grade, disseminated ore bodies. Usually ore bodies are mined by a combination of surface and underground methods. Initial mining is by surface methods, but as mining deepens, the amount of waste to be removed increases .
Openpit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore. An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding. The ore is crushed, then ground into powder. Concentrating. The ore is enriched using a process called froth flotation.
