Mineral Reserve Estimation In The Real World

Mineral Reserve Estimation In The Real World

Marcelo Godoy

��

The document summarizes best practices for mineral reserve estimation, including: - Using CIM definition standards which classify resources and reserves. - Involving multiple technical disciplines in the estimation process. - Considering modifying factors like mining methods and costs. - Selecting an appropriate commodity price and cut-off grade. - Clearly stating the mineral reserve statement and audit trail to allow reproducibility.

Mineral Resources and case study

Mineral Resources and case study

Manpreet Singh

��

This document discusses mineral resources and mining. It begins by defining mineral resources and providing an overview of India's national mineral scenario. It then lists some of the major metal reserves around the world and their common uses. The document estimates the life expectancies of various mineral resources based on reserve size and usage rates. It also outlines where in India certain key minerals like iron, coal, copper, etc. are located. The effects of different types of mining like surface and underground on the environment are discussed. The document concludes with a case study on mining and its impacts in Udaipur, India.

Geology Department, Faculty of Science, Tanta University

��

This document provides an outline for a lecture series on mining geology. It introduces key concepts related to mining, including definitions of mining, minerals, and ore deposits. It discusses various types of ore deposits and characteristics that determine their economic viability, such as grade, shape, depth, and stability. The document also lists topics that will be covered in each lecture, including ore mineralogy, the mining cycle, resource classification, mining methods, processing, waste management, and environmental issues. The series aims to give students a non-technical overview of the mining and mineral extraction process.

This document provides an outline for a lecture presentation on open pit mining methods and planning. It discusses key parameters such as bench height and geometry, cutoff grade calculation, and factors affecting open pit stability. The presentation covers the basic concept of open pit mining, how overburden is removed, and machinery used such as trucks, shovels, and drills. Diagrams illustrate typical bench terminology and pit slope angles. The importance of optimizing the pit design is addressed through considering elements like production scheduling, waste disposal, and ultimate pit limits.

Lecture 4: Underground Mining

Lecture 4: Underground Mining

Geology Department, Faculty of Science, Tanta University

��

The document discusses underground mining methods. It begins by explaining that the choice of mining method depends on characteristics of the orebody like thickness and dip, as well as the competency of surrounding rock. It then provides details on various hard rock and soft rock underground mining methods. These include longwall mining, room-and-pillar, blast mining, shortwall mining, and coal skimming for soft rocks. For hard rocks, methods include various stoping techniques, longwall mining, and caving methods. Stoping is defined as the process of extracting ore by leaving behind an open space called a stope.

Open pit mining involves digging a large hole or pit at the earth's surface to extract ore deposits near the surface. Overburden or waste rock is removed to expose the ore body, which is then extracted using large excavating equipment like shovels and haul trucks. Ore is transported from the pit either by truck or conveyor belt to a processing facility. Open pit mining provides high productivity and low costs but requires significant capital investment and can have large environmental impacts due to the large scale of surface disturbance. It is best suited to deposits that are relatively shallow and large in area.
