The Kalagadi Manganese Mine
The mine is situated West of Hotazel, off the R31 Road, Northern Cape. The mine is constituted out of three contiguous farms namely, Umtu 281, Olive Pan 282 and Gama 283, making a total area of 6300ha. It is a mechanised trackless board and pillar mine. This mine complex comprises the shaft complex, the ore preparation plant, sinter plant and bulk infrastructure. The mine has the capacity to produce 3million tonnes of manganese ore at a grade of 36-38% manganese and sinter at a grade of 44% – 48%.
Infrastructure
Key buildings on the mine complex above the shafts which serve mining operations and underground plant are:
Administration building, substations, workshops, refuge bays, conveyor belts, water pumps, winder gear, etc. The mine shaft winder house (machinery control room) containing cables, sinter plant / furnace, ore preparation plant, explosive storage, railway operations (the mine has 23km of its own track), power line of 132kV (property of Eskom) / substation of 40MVA, administration office building, 9 x 800KW Generators, multiple transformers, staff canteen, 2 x 60000L diesel tanks, water reservoir of 17 million liters, a maintenance workshops, sprinkler pump house, the staff accommodation and canteen block and the main security office at the front gate.
The Underground Mine
The shaft complex consists of two vertical shafts, the main shaft and the ventilation shaft. The main shaft is 9m in diameter, reaching a depth of 350m below surface. The ventilation shaft is 6m in diameter, reaching a depth of 317m. The two shafts are joined at the production level (281m) and the loading level (317m). The shallow depth means that there is lower seismic risk and lower rock temperatures that do not require refrigerated ventilation.
The main function of the shaft is the hoisting of workers, material and ore. The ventilation shaft is used for return ventilation and serves as an emergency exit.
Ore Processing Plant (the largest Mn sintering plant in the world)
The ore is processed through the ore preparation plant preparing the feed for the sinter plant. The ore is fed from the Ore Preparation plant through conveyor belts.
Sinter Plant
Kalagadi beneficiate the ore to produce 2.4 million tonnes of sintered manganese at a grade of 44-48% manganese. The difference between the sintered output tonnage and the 3 million tons of ROM ore is essentially the CO2 and moisture that is driven off from the Manganese Ore, which upgrades the Manganese content of the Ore.
Kalagadi sells its sinter product on both the South African and International market.
Roads and the Railway load out station
The site has a constructed 9.5km access road linking to the R31 main road, a Rapid Rail Load Out station and an electrified rail spur to ensure the efficient loading of bulk load trains and access to the main Hotazel Port Elizabeth Rail Corridor.
Other infrastructure
The mine has a 2 x 132kV Power Line from Sishen to the Umtu Complex and the Sub-station, and an 11km water pipeline to the Sishen / Blackrock / Sedibeng water supply line. We have a 6km rolled out fibre network.
The mine started production of the Manganese Ore in March 2018 with the plant being operated 24/7 throughout the week, with written permission to operate on Sundays. It is capacitated through a team of just over 960 Kalagadi permanent staff members.
简介
Kalagadi锰矿位于霍塔泽尔（Hotazel）以西，北开普省R31公路旁。该矿由三个相邻的农场组成，即Umtu 281，Olive Pan 282和Gama 283，总面积为6300公顷。这是一个机械化的无轨板柱矿。该矿场包括竖井，选矿厂，烧结厂和基础设施。该矿山产能可达300万吨锰矿石，品位为36-38％锰，烧结矿品位为 44％-48％。
基础设施
竖井上方矿山综合体中用于采矿和地下工厂的主要设施有：
行政大楼、变电所、车间、避难所、传送带、水泵、卷取机等。 包含电缆的矿井卷取机房（机械控制室）、烧结厂/熔炉、选矿厂、炸药库、铁路运输（ 矿有近 20 公里自己的轨道），132kV 电力线（为Eskom 资产）/40MVA 变电站，9 x 1000KW 发电机，多台变压器，员工食堂，2 x 6万升柴油罐，1700 万升水库 、维修车间、洒水泵房、员工宿舍和员工餐厅以及位于入口处的主要安全办公室。
地下矿井
竖井综合体由两个竖井组成，即主轴和通风井。 主轴直径9m，深度达地表以下350m。 通风井直径6m，深度317m。 两个竖井在生产层 (281m) 和装载层 (317m) 处衔接。 较浅的深度意味着较低的地震风险和较低的岩石温度，不需要冷藏通风设施。
竖井的主要功能是升降作业人员、物料和矿石。 通风井用于回风，并作紧急出口备用。
选矿厂（世界上最大的锰烧结厂）
矿石经过选矿厂加工，为烧结厂准备进料。矿石通过传送带进入选矿厂。
烧结厂
Kalagadi 对矿石进行选矿，以生产 240 万吨烧结锰，锰品位为 44-46%。烧结产出吨位与 300 万吨原矿的主要差异在于烧结后锰矿中的二氧化碳含量和湿度减少，提高了锰矿品位。
Kalagadi 在南非和国际市场上销售其烧结矿。
公路和铁路卸货站
该矿址有一条连接R31主干道的9.5公里长的通道，一个快速铁路卸货站和一个电气化铁路支线，以确保散装列车高效装载和通往Hotazel伊丽莎白港主铁路走廊。
其他基础设施
该矿有一条从锡申（Sishen）到乌姆图（Umtu）综合电站和变电站的2 x 132kV电力线，以及一条通往锡申（Sishen）/黑岩（Blackrock）/塞迪本（Sedibeng）供水管线的11公里输水管道，同时还有一个6公里的光纤网络。
该矿山于2018年3月开始生产锰矿，全天24小时运营，周末无休，并获得了周日开工的准许文件。960 名的终身员工组成的团队为该矿山提供运营支持。
