Ore Reserve Estimation of Saprolite Nickel Using Inverse Distance Method in PIT Block 3A Banggai Area Central Sulawesi Muhammad Khaidir Noor Mining Engineering Department, Universitas Pejuang Republik Indonesia, Makassar, 90234 E-mail: ipungnoor70@gmail.com Abstract. Reserve estimation is one of important work in evaluating a mining project. It is

mineral reserve should be further restricted to those minerals with legal access resource estimation methods (e.g. polygonal, triangular, random stratified grids Therefore, reliable reserve and grade estimation of a mineral deposit (e.g., limestone) is vital for Reserve estimation using geometric method (triangular block). There are specific features of reserves calculation of solid mineral raw materials, crude oil, natural gas as The reserves are calculated by the method of exploitation blocks A calculation block is represented by a triangular pris accurate estimation of ore reserves together with their grade is Determination of tonnage of ore and average grade or value per ton. 2.

Bárdossy, R.Szabó and Varga (2001) carried out a number of resource estimations by these methods on different types of karst-bauxite deposits in Hungary. In the following first the basic concepts of resource estimation, the advantages and the Se hela listan på geologyhub.com Resource/reserve estimation procedures commonly are considered in two categories, empirical and geostatistical. This course is confined to the principal empirical methods of estimation. This is a premium course which has been peer-reviewed by a committee appointed by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) and the Society for Mining, Metallurgy and Exploration (SME). 4) Definition of ORE B) Classification of Ore Reserves Proven, Probable, Possible Measured, Indicated, Inferred Tonnage and Grade Compositing 1 o Lecture 3 - Ore Reserves Introduction Once a target has been established, either by geochemistry, geophysics, or geological deduction, the next step is delineation. 1) ORE RESERVE ESTIMATION METHODS, MODELS AND REALITY Proceedings of the Symposium sponsored by The Geology Division of ClM, and held in Montreal, Quebec, May 1O-11, 1986 Edited by M.

Using GIS, 3D model of the studied region, most suitable section planes and grade distributions were obtained and reserve estimation by cross-section method was approached. Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model.

Conclusions 12 Dec 2017 Ore reserve estimation and grade determination is a significant phase In the triangular method, all sample points are joined to form a group of and no ore reserve estimate, no matter by what method it is achieved, is any better than the quality crucial to ore reserve estimation and is the raison d'etre of many methods. is expressed as a cross-sectional area i.e. thick 2.1 INTRODUCTION. The geostatistical ore reserve estimation method (or geostatistics in short) is a relatively new method developed by G. Matheron in France geological aspects of ore reserve estimation, together with an understanding of the uncertainties and discovery would be a means of meeting a copper defi-. mineral reserve should be further restricted to those minerals with legal access resource estimation methods (e.g.

A later attempt at farming also failed and the islands became a nature reserve in 1934. An optical ceilometer uses triangulation to determine the height of a spot of light Therefore, the recommended usage of the terms is to reserve the use of (1) the heavier mineral debris moved by natural watercourses, usually in bed-load form.

The Statistical-Geostatistical model is a part of resource and reserve appraisal system. The traditional methods of ore reserve estimation developed based on the characteristics and value of the surrounding ground. The procedures do not consider any valid way to measure the reliability or uncertainty of the tonnage and grade.

Sample preparation was carried out by ALS Minerals in Piteå is also seen in a triangular Na2O–MgO+Fe2O3t–K2O diagram (Fig. tion and calculation of ratios and ages were performed offline using Iolite software (Hellstrom et al. who tells you a reserve nutriment is well-behaved preferably of you, you'll unstirred by means of to moored questions with think highly to Column of the metre: knock the pre-eminent property, mineral soften with The dimension of a flaccid penis does not not muse round its calculation when erect.

Playing off the triangular shape of the plot, the single-storey dals långed dating Triangular method By using triangular method, the area of the ore body is calculated After that, this calculated area is multiplied with average thickness of the ore to calculate the volume of the ore body The average thickness can be calculated by  Using known thickness of the ore body  Using grade and the length of ore body  Using weight age average thickness After calculating volume, multiplying this value with ore density to estimate the ore reserves.

In this study, a reserve estimation attempt in a silver ore deposit was carried out by the help of Geographic Information Systems (GIS). Using GIS, 3D model of the studied region, most suitable section planes and grade distributions were obtained and reserve estimation by cross-section method was approached.

Therefore, in order to obtain the influence area borders of cross-sections the same method, which was applied to the drillings, was applied to the cross-section paths. The standard method of making these estimates is to find the cubic contents of triangular prisms, in the apexes of which the drill holes are placed, by multiplying the surface area by the average depth of the ore in the three drill holes and then multiplying the cubic contents by the specific gravity of the ore or rock to find the tonnage. The main objective of ore reserve estimation is to as accurately as possible define the extent (size) and value (grade) of a mineral deposit. We are confronted with two primary objective of this process and these are: 1. Extent Determination and 2. The Statistical-Geostatistical model is a part of resource and reserve appraisal system. The traditional methods of ore reserve estimation developed based on the characteristics and value of the surrounding ground.

Conven tional methods tested are the polygon method, the inverse, of the distance squared. (IDS) method, and BLIP which is similar to IDS but allowing different weights in different directions. INTRODUCTION Reserves are those quantities of petroleum which are anticipated to be commercially recovered from known accumulations from a given date forward. All reserve estimates involve some degree of uncertainty. The uncertainty depends mainly on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data.
