Embodiment 1

[0062] Step 1. Determine the location of the deposit:

[0063] The first lateritic nickel mine is located about 2km south of Subayin Village, East Halmahera County, Northeast Maruko Province, Northeast Indonesia. According to the previous geophysical, geochemical, exploratory well and drilling data, the general location of the ore body was preliminarily determined. The system Arrange the drilling project, carry out geological records, sampling, testing and analysis, and further identify and determine the spatial location of the deposit: the mining area is located at the junction of the north slope of the main peak of Wadowaduo Mountain and the alluvial plain of the Subayin River, and the terrain is relatively gentle. Qiutai, the plane position is between 114000-117000 north coordinates, 403000-405000 east coordinates, the ore body occurrence elevation is 50m-400m, the ore body area is about 4.85km2, and the ore deposit is produced in ultrabasic rock In the middle and upper part ...

Embodiment 2

[0142] Step 1. Determine the location of the deposit:

[0143] The second lateritic nickel mine, located 15km northeast of Surigao City in Mindanao, Philippines, preliminarily determined the general location of the ore body and systematically arranged the drilling project according to the previous geophysical prospecting, geochemical prospecting, well exploration and drilling data. Carry out geological records, sampling, testing and analysis, and further identify and determine the spatial location of the deposit: the mining area is located in the Lutawon Basin (Lutawon) in the northern part of Nonok Island, and the geographical coordinates of the mining area are located at 125°38' east longitude and 9°51 north latitude ′, the plane position is between 1,086,000-1,093,000 north coordinates, and 563,000-576,000 east coordinates, the ore body occurrence elevation is 70m-280m, and its mining rights area is about 43.72km 2 , the deposit is produced in the middle and upper part of t...

Embodiment 3

[0177] Step 1. Determine the location of the deposit:

[0178] Brgy.Massin, located in New Panay Island, Brooks Point City, south-central Palawan Province, Philippines, is the second lateritic nickel mine. Based on previous geophysical prospecting, geochemical prospecting, exploratory well and drilling data, the general location of the ore body is preliminarily determined , systematically arrange the drilling project, conduct geological records, sampling, testing and analysis, and further ascertain and determine the spatial location of the deposit: the central coordinates of the mining rights area: 8°56′47.428″ north latitude, 117°53′47.500″ east longitude, the mining rights area Located in the foothills of the Mantalingahan Mountains, the northern part of the mining rights area is a steep ridge, the mining area is 75m-500m above sea level, and the mining rights area is 28.35km 2 , the ore deposit is mainly produced in peridotite, mainly dunite and peridotite, which have under...

Abstract

The invention discloses an analysis method for mining potential of a water-containing silicate type laterite nickel ore, and belongs to the technical field of deep prospecting of water-containing silicate type laterite nickel ores in southeast Asia. The problem that during drilling of the water-containing silicate type laterite nickel ore deposits in southeast Asia, saprolite is not easily penetrated, and consequently, some laterite nickel ore resources from the saprolite layer to base rock are lost is solved. The analysis method comprises the steps that the deposit position is determined; theelement content of all ore beds passed during drilling is tested; the ore bed reached by drilling operation is judged; the depth from the ore bed reached by drilling operation at present to the bedrock surface is deduced; the ore type of the water-containing silicate type laterite nickel ore is judged; and a subsequent smelting machining technology is selected. According to the analysis method, whether drilling reaches the bedrock or not can be judged according to drilling analysis, whether potential resources still exist in the same depth of the deposit or not is further judged, the resourcetotal amount of a later excavation project are overall predicted, and resource development is conducted more reasonably and more comprehensively.

Description

technical field [0001] The invention belongs to the technical field of deep ore prospecting of hydrous silicate type laterite nickel ore in Southeast Asia, and specifically relates to a method for analyzing the mining potential of hydrous silicate type laterite nickel ore Background technique [0002] Laterite-type ores account for about 60% of the world's total nickel resources, and are mainly distributed near the equator. They have the advantages of rich resources, low exploration costs, and extremely low mining costs. According to the characteristics of ores, they can be divided into hydrous silicate type and clay silicate type. There are three types of salt type and oxidation type, among which the hydrous silicate type deposits are mainly distributed in New Caledonia, Indonesia, the Philippines and other countries. If it is not possible to penetrate the decayed rock layer to reach the bedrock, some higher-quality laterite nickel ore resources will be lost. [0003] Ther...
