Iron Ore production in the Pilbara Rio Tinto
Activities involved in finding, mining and processing iron ore at our Pilbara operations have been simplified in the following diagram Rio Tinto operates 11 iron ore mines in the Pilbara and the specific sequence of activities varies from mine to mine Excellence in planning, scheduling and quality control are fundamental to the processThe fragmentation of rock is fundamental to mining It is the first preparatory stage in the extraction process – making rock small enough and loose enough to be efficiently excavated But this simple statement underestimates how important Rock Fragmentation by Blasting Orica Mining Services Lecture Overview Introduction Pit Geometry Interaction deposit geometry Design and management Overall process Interaction of distinct operations Machinery – Drill Rigs, Loaders, Excavators etc General appraisal Blasting Drilling of Open Pit Mining Hardrockdrills

Iron Ore: From Mining to Processing to Dust Control
Iron ore is a rock or mineral from which metallic iron can be extracted economically It constitutes 5% of the earth’s crust Viable forms of ore contain between 25% and 60% iron Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into ironmaking blast furnacesThe act or process of creating holes in rock mass for later filling with explosive and blasting Drill and Blast The combined cycle of drilling and blasting, often classified as a discrete process and cost centre in most mines Drill Pattern A group of blastholes on a bench or face form a drill pattern E Effective EnergyBlasting Principles Orica conducting a case study in Chador Malu iron ore mine in Iran KEYWORDS Stability, Final wall, Presplit, Drilling, Blasting, Open pit INTRODUCTION Estimating the safe wall angles of mines is necessary to calculate oretowaste ratios during the FINAL WALL STABILITY IN METAL OPEN PIT MINES

Geophysics applied to the optimization of blasting design
The extracted ore comes from the enrichment of precambrian banded iron formations (BIFs) (Beukes et al, 2003) The usual model of blasting applied in production benches, with blast drill holes distributed homogeneously, can leave compact rock boulders, reducing the rate of extraction and grinding, thus, impacting the daily production of iron ore Studies on Uniaxial Compressive Strength, Uniaxial Tensile Strength, Young’s Modulus, Poisson’s Ratio of Iron Ore in relation their Influence in Optimum Blasting process of Mining Activities (PDF) Studies on Uniaxial Compressive Strength, Uniaxial FINAL WALL STABILITY IN METAL OPEN PIT MINES USING PRESPLIT BLASTING *Kazem Oraee 1,Ali Mozafari 2, Arash Goodazi 2, and Nikzad OraeeMirzamani 3 this process has great economic value for mine operators This paper aims to illustrate the technical aspects conducting a case study in Chador Malu iron ore mine in Iran FINAL WALL STABILITY IN METAL OPEN PIT MINES

Janse says mining companies selling a type of iron ore blend consisting of a specific grade cannot afford making the mistake of putting the highgrade ore in the medium grade stockpile “In an The ore in the Svappavaara field's active openpit mine, Leveäniemi, is extracted by mining the ore in descending levels The thickness of the slabs, known as the bench height, is 15 metres, and the slabs are worked downwards In the first stage, the ore is extracted at one level before moving down a step (15 metres), after which the ore is Our openpit mines LKAB Blasting is a highly variable process and movement of the ore during blasting can cost mines millions of dollars in lost revenue per year from ore loss BMT’s solution provides customers with accurate blast information that is used BLASTING: Hexagon acquires Blast Movement
