Xstrata Alloys has adopted the 2004 Australasian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves (the JORC Code) as its mandatory standard for the estimation of public reporting of Mineral Resources, Ore Reserves and Exploration Results.
The estimation process is further based on the Xstrata Alloys procedure “HSEC-G-08-The Procedure for the estimation of Mineral Resources and Ore Reserves”.
The Ore Reserves and Mineral Resources are declared as at the 30th of June 2008, unless stated otherwise for the particular commodity.
This statement covers four ore types currently being mined and beneficiated by Xstrata Alloys. The ore types are:
Chromitite
Vanadiferous Magnetite
Quartzite
PGE mineralized chromitite ore
The Ore Reserve and Mineral Resource information in the tables on the following pages is based on information compiled by Competent Persons (as defined by the JORC and SAMREC Codes).
The Competent Person initials have been included after each mine or project for which the Competent Person have been responsible. Each of the Competent Persons has the appropriate professional membership and the relevant experience in relation to the Mineral Resources and/or Ore Reserves being reported by them to qualify as a Competent Person as defined in the JORC and SAMREC Codes. The Competent Persons have consented to the inclusion in the report of the matters based on their information in the form and context in which it appears. Copies of the consenting letter are kept with the legal department of Xstrata Alloys.
Metric units are used throughout. All data is presented on a 100% basis. All tonnage and grade information has been rounded to reflect the relative uncertainty in the estimates; there may therefore be small differences in the totals. Mineral Resources are reported inclusive of those Mineral Resources modified to produce Ore Reserves.
Commodity prices and exchange rates used to estimate the economic viability of Ore Reserves are based on long term forecasts applied at the time the estimate was calculated.
The detail background information for the estimation of the Mineral Resources and Ore Reserves can be requested from Xstrata Alloys.
Mineral crusher and ore crusher
In the mineral resources mining indsutry, NFLG can can supply you mineral crusher or ore crusher used for crushing mineral resources in mining plants. Such as mineral jaw crusher is the most widely used crushing equipment in primary crushing plants. The secondary crusher machinery includes gyratory crusher or cone crusher with spring, hydraulic, hcs90 types.
Definitions
The following definitions (as per the JORC Code 2004), have been applied in estimating the Ore Reserves and Mineral Resources position of the Xstrata Zinc disclosed within this document.
Mineral Resource: a concentration or occurrence of material of intrinsic economic interest in or on the Earth’s crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.
Inferred Mineral Resource: that part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be limited or of uncertain quality and reliability.
Indicated Mineral Resource: that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed.
Measured Mineral Resource: that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence. It is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are spaced closely enough to confirm geological and grade continuity.
Ore Reserve: the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined.
Appropriate assessments and studies have been carried out, and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction could reasonably be justified. Ore Reserves are sub-divided in order of increasing confidence into Probable Ore Reserves and Proved Ore Reserves.
Probable Ore Reserve: the economically mineable part of an Indicated, and in some circumstances, a Measured Mineral Resource. It includes diluting materials and allowances for losses which may occur when the material is mined. Appropriate assessments and studies have been carried out, and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction could reasonably be justified.
Proved Ore Reserve: the economically mineable part of a Measured Mineral Resource. It includes diluting materials and allowances for losses which may occur when the material is mined. Appropriate assessments and studies have been carried out, and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction could reasonably be justified.
Mineral processing plants
Mineral processing plants are mainly consisted of crusher, grinding machines, screens, feeders, conveyors etc. In some cases, we need mineral resources’ powder for industrial usage, so we need stone milling equipments for grinding process. Mineral mill or mineral grinders mainly include ball mill , Raymond grinder machine, vertical roller mill, trapezium grinding mill etc.
