PETRA DIAMONDS FINSCH MINE DATA CAPTURE
ore pass remediation at their Finsch mine. BACKGROUND Headquartered in Jersey in the Channel Islands, Petra Diamonds has an interest in eight mines in South Africa and Tanzania, with a combined production output of around 3,700,000 carats a year. The company’s Finsch underground mine, in South Africa’s Northern Cape province, isGraphical Abstract. 1. Introduction. Sensor-based ore sorting is gaining increased attention both within and outside the mining industry, as it is leaving the state of pilot plant scale and technology road-mapping, and an increasing amount of equipment is installed in high-capacity production scale environments.Minerals Free Full-Text Sensor-Based Ore Sorting Technology in

Assessment and Control of Ore Dilution in Long Hole Mining: Case
Abstract. Unplanned ore dilution has a direct and large influence on the cost of a stope, and ultimately on the profitability of a mining operation. This paper presents the results of an examination of factors influencing ore dilution in a blasthole stoping environment. For the study, a comprehensive database was established, incorporatingTrona is a hydrated double salt of sodium carbonate and sodium bicarbonate, Na 2 CO 3 NaHCO 3 2H 2 O. It is the primary ore mineral that is processed into natural soda ash, which accounts for approximately 30% of the world’s total soda ash production [].The largest reserves of trona are located in the Green River Basin covering Coarse Beneficiation of Trona Ore by Sensor-Based Sorting

Performance Evaluation of Underground Mining Machinery: A Case Study
Case Study. In this research, five numbers of LHD machines deployed in an Indian underground lead and zinc mine. The considered machines for the present analysis are made from M/s The Sandvick Company Limited with 17 tonne bucket capacity and named as LHD1, LHD2, LHD3, LHD4, and LHD5.The T-3000 roadway was driven in the trona ore body for the first stope. Load and convergence measurements were carried out at seven stations installed in main drift (T2000) and roadway (T3000).Determining the stress and convergence at Beypazari trona field

Sampling Broken Ore Residues in Underground Gold Workings
The underground mining process typically results in some of the metal inventory remaining as a broken residue within mine workings. Up to 0.5 m of broken ore may be left on the floors of development drives and in stopes. It is possible that this broken ore contains 5% or more of the original metal in the ore reserve, which will have a Case study of controlled recirculation at a -and-pillar coal mining, with permissible face equipment inby and diesel-powered, rubber-tired support equipment outby.

Mine Productivity Issues: A Case Study of Mopani Mindola IJERT
Currently, the advance per round at MSV Mine is at an average of 2.8m per round with a relative advance of 90% which give an average socket length of 0.9m. The allowable socket length is approximately 0.3m. The round length is 3.7m and the length of the drill rode (jumper length) is 3.7m with a 0.2m of collaring.The study area is near Beypazari town that is 100 km northwest of Ankara, and the Beypazari natural soda (trona) field is located in an area of 8 km 2, which is 20 km northwest of Beypazari town center (Fig. 1).The Beypazari natural soda (trona) field exists in the lower parts of the volcano-sedimentary sequence of the neogene basin and Impact of the mechanical characteristics of weak rocks and trona ore

Coarse Beneficiation of Trona Ore by Sensor-Based Sorting
other sedimentary species []. Conventional underground 3 mining methods such as room and pillar and longwall mining have been used since the 1940s, where run-of-mine (ROM) ore is extracted and hoisted to the surface for processing. Conventional processing of trona ores in Green River entails a sequence of primary size reduction, calcination atThe study encompassed preparation of a run-of-mine (ROM) Green River ore sample, selection of 25–75-mm-sized specimens, imaging of the specimens by x-ray transmission (XRT), color, and laserCoarse Beneficiation of Trona Ore by Sensor-Based Sorting

World’s largest trona deposit emits enough methane to power
When trona ore is extracted from underground mines, the fracturing of the rock releases methane While soda ash can be manufactured synthetically, about 35% of the world’s supply comes fromThis paper evaluated the suitability of locally-sourced Trona, as a mud additive in drilling mud. Trona is known chemically as Sodium Sesquicarbonate or Sodium Hydrogen Carbonate. A distinguishing factor in this research work was the purification of Trona by extracting the compound of interest (Na2CO3) from it using the monohydrate process.Study of the Potential of Sodium Carbonate Extracted from Trona
