A critical component to any feasibility study of an open-pit mining project is determining the ultimate pit limits and the optimal mining phases (pushbacks). Today, block models are the most commonly used technique for calculating mineral resources and reserves (Krzemień et al., 2016; Riesgo García et al., 2019; Sterba et al., 2020).

Effects of mine and mineral type were observed, with underground milling costs being significantly less than open pit milling costs and gold mines occupying a significantly larger share of mine operating costs than copper-containing mines. The overall relative operating costs were found to be in the ratios between (43:43:14) and (45:45:10 ...

However, the level of eco-environmental destruction in open-pit mining regions is ten times higher than in other mining areas (Zhou et al., 2018). According to statistics in 2018, China has 67,700 mines with an annual mining capacity of more than 30 billion tons, which destroy over 4 million hectares of land, and tailings waste rock …

Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.

1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The. Read More

Open pit mining -- or strip mining -- is an extraction process for ore or fossil fuels that takes place at the surface of a mining site. Worldwide, 40 percent of mining occurs at the surface, according to Greenpeace International. ... All of these improvements to efficiency work to reduce the cost of mining using an open pit. Greater Safety ...

At the initial stages of a cost estimation, the focus will be on the preliminary design of the mine, mainly on how to access the orebody. Then, most of the costs associated with preproduction are associated with the underground developments required to access the orebody. These estimations also provide an indirect insight on the quantity …

This paper analyzes an open pit gold mine project based on the O'Hara cost model. Hypothetical data is proposed based on different authors that have studied open pit gold projects, and variations are proposed according to the probability distributions associated to key variables affecting the NPV, like production level, ore grade, price of …

There was a fair amount of research that went into gathering all the costs and dimensions needed to give potential miners an idea of the financial implications of running an open-pit operation. One of the more unique features of this financial model is the ability of the user to enter the % of a given ore they expect to have in each tonne of ...
