In this study, the amount of boulder produced in blasting operations of Golegohar iron ore open pit mine, Iran was predicted via multiple regression method and artificial neural networks.
Prediction of produced boulders (oversized crushed rocks) is a key parameter in designing blast patterns. In this study, the amount of boulder produced in blasting operations of Golegohar iron ore open pit mine, Iran was predicted via multiple regression method and artificial neural networks.
If an iron ore mining company has an annual ore production of 30 million tons with a grade of 64%, the total ore loss per year will reach 6 million tons of iron ore. What a figure for ore loss! We will see that rock fragmentation can be largely improved by blasting, and a better fragmentation can increase both productivity and ore recovery and .
Today, blasting is still used at the mines to release iron ore from the earth, but in todays world, its much safer than years past. One of the big changes is the products used, said Ron Shoden, general manager of Viking Explosives in Hibbing. Shoden has spent more than 43 years in the mining industry. Its not like the old days .

The company's iron ore mine is situated at Tensa valley in district Sundargarh, Odisha. The mine partially fulfills its requirement of iron ore for producing sponge iron. Produced as part of the company's backward integration plans to make it self reliant, the iron ore ensures consistency in the quality of raw material used in sponge iron kilns.
Bender (1999) defined production blasting as the type of blasting that is designed to fragment a predetermined volume of rock; widely spaced holes are drilled and fired in a controlled delay sequence.
National Institute of Technology Rourkela This is to certify that the thesis entitled Optimization of Blasting Parameters in Opencast Mines submitted by Sri Manmit Rout (Roll. No.: 10305019) and Sri Chinmay Kumar Parida (Roll. No.: 10305017), in fulfillment of the requirements for the award of Bachelor of.
Since the ore to overburden ratio is very high at initial stages of mining the main concentration will be on removal of over burden. Float ore occurs in consolidate earth comprising of soil, soil and murrem and iron ore boulders / pebbles / fines. The insitu ore will be worked by 7.0m benches drilling will be DTH hydraulic.
One common problem for blasting in iron ore mines with significant weathering is the occurrence of large blocks of hard rock mixed with softer material. This situation causes a problem for blasting design and sometimes produces large boulders of rock that require a secondary blasting, as well as excavation difficulties. To minimise this situation, geophysical.

This research examines optimization of blasting parameters for economic production of granite aggregates in Ratcon and NSCE quarries located atIbadan,OyoState. Samples were collected from the study areas for the determination of rock density and porosity. Schmidt hammer was used for in situ determination of rock hardness. Uniaxial compressive strength of in situ rock was estimated from .
iron ore mine and is a very valuable EBIT lever. Therefore the ability to control fragmentation for the end product is valuable. Similar requirements also exist in the industrial minerals sector. Conclusion #4: Controlling energy during blasting can realise higher profits through higher value end product. Fragmentation control for production.
Sep 09, 2016nbsp018332blasting the first stage of the crushinggrinding process in a production facility begins with blasting of the ore body, where the blasted material is composed of a very wide range of sizes. very fine material from the zones surrounding the blast holes, to large boulders exist, which require additional breakage.

From ore to steel ArcelorMittal. The steelmaking process starts with the processing of iron ore. The rock containing iron ore is ground and the ore is extracted using magnetic rollers. Fine-grained iron ore is processed into coarse-grained clumps for use in the blast furnace.
Iron Ore Processing for the Blast Furnace. blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").
