Abstract

The utilization of low rank coal (lignite and sub-bituminous) especially gasification is part of thedevelopment of coal conversion in Indonesia as drivers of the increase in value-added coal.Gasification is a process of change in the solid fuel into gas. In contrast to combustion, gasificationprocess is the process of breaking the carbon chains to form other chemical elements or compounds.This research was conducted by looking at the effect of the type of maceral, mineral and geochemicallow rank coal in the Kutai Basin. It also saw the effect of operating conditions (time and temperature),the condition of pyrolysis and gasification catalyst, so it will know the volume of the gas content of CH4,CO, CO2 and H2 results of the low rank coal gasification.

Abstract

This research was conducted in the area Tanjung Buli, East Halmahera regency. This area has ironore resources in the prospects for exploration to exploitation with data obtained using spaced borehole25meter. Point kriging method with software SGeMS (Standard Geostatistic Modeling software) usedfor assessing of iron ore resource with size of block model dimensions 41x23x205 and unit blocks25x25x1 (in meters). The results of the assessment point kriging method obtained estimated values ofFe and kriging variance value is then used for the classification of resources based on relative krigingstandard deviation (RKSD) as classification of resource measured, indicated, and inferred. The resultsof cross-validation of the assay data-Fe-Fe estimation data from point kriging method. The results ofresource assessment Fe of measured amounted to 3,081,125 tonnes, Indicated amounted to6,878,563 tonnes and Inferred amounted to 97,781,563 tonnes. The pattern of spread showed high Fecontent above 14.40% Fe dispersed randomly (varies) or local-local in units of small blocks.Correlation coefficient value showed of 0.89 so it has a strong correlation between the assay data-Fewith Fe estimation data.

Abstract

Study area is located in Mutiara and surrounding area, Samboja District, Kutai Kartanegara Regency,East Kalimantan Province. At coordinates 0° 56’ 43’’ - 0° 59’ 26’’ South Latitude and 117° 1’ 37’’ - 117°3’ 46’’ East Longitude or UTM N 9890500 - 9895500 and E 503000 - 507000. The objective of thisstudy is to identify geological conditions and the influence of geological structure toward to quality ofcoal in the study area. The stratigraphy of study area composed by 3 rock units and 1 unconsolidatedfrom old to young are Balikpapan sandstone unit (Middle Miocene - Late Miocene) deposited in LowerDelta Plain, Kampungbarusandstone unit (Late Miocene - Pliocene) deposited in Lower Delta Plain,and Quarter Alluvial (Holocene). From proximate analyses, coal seam Kampungbaru Sandstone Unitcontain low sulfur and low calories, and high total moisture due to presence of two normal faults fromsubsurface interpretation that formed simultaneously with peatification process on coal seamKampungbaru Sandstone unit. Those normal faults resulted water increase on peatificationenvirontment that caused aerobic bacteria can not completely ondestruction of plant components thatwill form high sulfur and low calories and high total moisture.

Abstract

Four samples of coal and two samples of carbonaceous shales at the Latest Eosen age were studiedabout the minerals contains relative to height of average sulphur values. The sulphur in coal Haloqformation samples are code HBG-1102 (3,55% adb), MMH- 0504 (0,95% adb), MMH- 05021 (0,91%adb), MDG-0703 (0,7% adb) and the sulphur in carbon shale Batuayau formation samples are codeMRH-0806 (0,35% adb) and MRH-0801 (3.25% adb). The two group of rock samples contain highsulphur with average 1,53% (adb) in Haloq formation and 1,78% (adb) in Batuayau formation. Analysisproximate, ultimate, and x-ray diffraction (XRD) were used for determine the coal compositions, thevalue of carbon (C), hidrogen (H), oxygen (O), Nitrogen (N), and sulphur (S), and expectation ofminerals in coal. The results of XRD were showed mineral zaherite, quartz, caolinite, beidelite weretransformed from smectite, and mineral nacrite were transformed from caolinite. Melanterite andmagnesiocopiate were secondary mineral of sulphate were indicated formed from oxidation pyriteinfluence. The presence of Melanterite and magnesiocopiate were indicated as caution of the highestaverage sulphur value in coal and carbonaceous shale samples.

Abstract

Land Clearing for tin ore mining on Bangka Island for hundreds of years produces mine ponds calledkolong. Water resources at the old age kolong have been utilized by the community as a source ofdomestic water, including the source of water by Regional Drinking Water Company (PDAM). Illegal tinore mining since 2000 until now by the community (unconventional mining) has caused pollution ofPDAM water resources by mining waste of tailings. Primary and secondary data collection has beendone on Kolong PDAM Tirta Bangka, PDAM Tirta Pinang and PDAM Sejiran Setason. Physical datacollection of water and sediments to obtain parameters of temperature, smell, soluble and suspendedsolids and turbidity. Chemical analysis of water and sediments including pH, heavy metal of Fe, Al, Pb,and Cu using AAS and XRF. Feasibility evaluation of the water using Permenkes RI Number907/Menkes/SK/VII/2002. Heavy metals were founded on all the water of kolong are Fe, Al, Cu andPb. Heavy metal in sediment are Fe, Cu, Pb, Sn and As. Kolong Merawang has a large distribution ofFe, Al, Cu and Pb in water and sediment. Al metal exceeds the threshold in Kolong Merawang andPedindang (1.01 mg/L and 0.35 mg/L). The Fe composition at all kolong sediment is very large innumber. The distribution of dissolved Pb metal in water exceeds the threshold at all kolong, especiallyon sediment of Kolong Merawang and Pedindang. Water resources at all kolong have met in physicalfeasibility but exclude their chemistry

Abstract

Tin ore washery Sn) is less than the maximum will affect the waste of precious minerals togethertailings resulting in increased levels of tin in the tailings. This is certainly a serious problem for thecompany, the impact of the loss will be visible both from time, labour, etc. And certainly not inaccordance with the target company based on Standard Operating Procedure (SOP). To determinethe levels of Tin (Sn) is still contained in the tailings, the tailings assessments conducted usingmicroscopic analysis.Tailings samples studied came from washery tailings back to the concentratefrom the mining and leaching earlier in Dredger (KK) and Ship Suction (KIP) is brought to the Tin OreProcessing Center (PPBT). Cassetrite or primary mineral Tin (Sn) dominant in the size fraction (+ 50# -20 #) with a percentage weight of 1.176%, and the largest number of samples contained in thetailings coming from Ships Suction (KIP) 4 that is equal to 2.61%. Cassetrite for the weightpercentage of all samples of the tailings is 3:09% and obtained his Levels is 2:44% Sn. The resultsobtained are presented in tables and graphs. Based on microscopic analysis and calculation of Sn inthe whole sample of tailings Dredger (KK) and Ship Suction (KIP), the results turned out to be not inaccordance with the Standard Operating Procedure (SOP) of the company is 1%.

Abstract

The position of Majenang-Bantarkawung region become important and strategic because has a lot ofmineral and coal resources. However, there is no effort in mining area regulation to optimalizationmanagement of mining resources who can useful for people prosperity. Mining zonation of Majenang-Bantarkawung make with weighting and scoring in determination of mining parameters thanprocessing the parameters with overlay method. The parameters are : Land height, Land elevation,Disaster-prone areas, Overburden thickness, Ground water, River area, Water infiltration areas,Forest areas and Agricultural area. According to overlay of 10 mining parameters, Majenang-Bantarkawung mining zonation can be divided into can be permitted to mined, can be permitted tomined with certain condition, and can’t be permitted to mined. Banyumas regency has 61 distributionof mining resources location. Cilacap regency has 75 distribution of mining resources location. Brebesregency has 53 distribution of mining resources location.
