The new conductivity model of the upper crust agrees well with the results from the seismic studies. Interpreting both independent data sets confirms the major features from the previous model, such as the thickness of the Revsund granites in the south, the existence of a structural basement with metasedimentary origin, and gives …

A review of the current state-of-play for a number of major deposit styles shows how geophysical data are being used at present to explore for the larger scale …

A combination of two or more geophysical methods for a particular investigation will ensure a more accurate outcome/result than a data set from any single geophysical method. Data from each geophysical method, if interpreted by several available procedures/techniques, enhances the acceptability of interpretation due to the …

ABSTRACT Nickel (Ni) and Cobalt (Co) deposits are important mineral resources, and China is the largest consumer of these resources. Magmatic, hydrothermal, sedimentary, and meta-sedimentary ore-bearing rocks are the most significant Co-Ni deposit types in China, accounting for 98% of the Co production. Thus, exploring the Chinese Co-Ni …

Most ore, however, is contained within hard rock that requires heavy duty crushing. Mobile jaw crushing machine processing ore. The goal of comminution is to crush the ore into small particles that contain only one mineral. Dry crushing ore to ~1-5 mm particles is carried out on crude ore by compression and impact force.

However, the geophysical and social conditions are quite different from Japan's ones. The material flow selected for the mining program, for example, has no economy under Japan's social condition. One of the key technologies necessary for improving the economy in Japan, a primary ore dressing of excavated SMS ores on the …

Purpose: Approbation of approaches to the assessment of seismic liquefaction of technogenic soils by geophysical data in Ukraine's tailing dumps of ore mining and processing enterprises.

The origin of the studied manganese deposits in Um Bogma area resembles the same ore in most of Africa; there are three theories that are defined (Gindy 1961, Nakhla and Shehata 1963, Saad et al. 1991), maintaining the view that the manganese ores are of epigenetic origin, which is a result of the activity of ascending mineralized …

At the same time, we need to look for ways to push the limits of existing technologies to better discriminate features at depth. At the AEGC, I shared the results of synthetic modelling as part of our multi-physics project highlighting the opportunity for improved discrimination of ore body targets by combining information from multiple …

HEM results are verified by ERT and RCPTU results. However, seismic refraction data suggest continuous bedrock below the landslide location instead of ruptured bedrock as suggested by HEM and ERT data. ...

The Paleoproterozoic Kristineberg mining area, northern Sweden: Results from integrated 3D geophysical and geologic modeling, and implications for targeting ore deposits

Ore-dressing methods fall naturally into two general subdivisions— (1) concentration methods and (2) direct-recovery methods (amalgamation and leaching or …

Geophysical data and their relationship to known geology. In 2005 the airborne gravity gradiometry data were acquired over the study area (Boa 6) ... This result also reveals that the iron-ore deposit is strongly controlled by the Gandarela syncline. The large estimated volume of the iron-ore mass seems to be controlled by the hinge zone …

The Paleoproterozoic Kristineberg mining area, northern Sweden: Results from integrated 3D geophysical and geologic modeling, and implications for targeting ore deposits

In the past decade, the applications of magnetotelluric method in the electric prospecting for ore bodies have been rapidly progressing. In the present work, we summarize the first results on this way. We discuss the specificity of the geoelectrical models in the problems of mining prospecting for ore bodies. The state-of-the-art …

Insufficient grinding may result in the loss of valuable minerals in tailings, over grinding wastes energy and produces slimes which also result in losses and are difficult to treat …

The document summarizes the key steps in the ore dressing (mineral processing) process. It describes four main steps: 1) Comminution which involves crushing and grinding ore to reduce particle size. 2) …

related to the multiplicity of sources that can cause geophysical anomalies. This feature is an implicit uncertainty in the discussion that follows. Environmental geophysics, like exploration geophysics, requires complimentary geophysical surveys integrated with geochemical and geologic insight. This presentation first summarizes geophysical ...

This shows that the prospecting results can effectively screen the ore prospecting space and obtain a meaningful prospecting target area. The neural network method prediction results are shown in Fig. 10. Result statistics show that the proportion of known orebodies within the predicted area is 85.38% (368/431) in the 2D projection plane.
