Nine Mines migrate to the Electronic Reporting System Nine Major mines on the Copperbelt and North-Western Provinces have been migrated from manual monthly minerals production reporting to the electronic submission of reports on the Mineral Output Statistical Evaluation System (MOSES). î ˘e migration of mines to electronic reporting is a major milestone achieved under the Mineral Value Chain Monitoring Project (MVCMP) and the Mineral Production Monitoring Support Project (MPMSP) that have been tasked to develop an integrated online Mineral Output Statistical Evaluation System Speaking in Lusaka, Ministry of Mines and Minerals Development Director of Minerals Development Mooya Lumamba says the nine mines starting from September 15, 2017 will no longer submit any manual monthly production reports. î ˘e mines that have been migrated are Chibuluma Copper Mine, Chambishi Metals, Chambishi Copper Smelters, Luanshya Copper Mines, Lubambe Copper Mines, Lumwana Copper Mining, FQM Kalumbila Copper Mine, Sino Metals and NFCA Copper Mining Company.

According to Mr. Lumamba, the other three major mining companies; FQM Kansanshi Copper and Gold Mine, Konkola Copper Mines, and Mopani Copper Mine will be migrated to electronic reporting in October 2017.

And Z ambia Revenue Authority (ZRA) C ommissioner for Modernisation and Corporate Strategy Dingani Banda has applauded the

In addition, improving rainfall and rising dam levels in the country will ease some of the power shortages which have been experienced in recent quarters.

Zambia is highly dependent on hydroelectric power generation and water levels at the Kariba hydroelectric dam have already risen from 31% in May 2017 to 54% in May 20 17, which should help provide miners with ample power supply in H2017.

Rising prices to boost production Another key driver of Zambian strong copper production this year will be the positive trajectory of prices in 2017 relative to last year.

Since touching lows of US$4, 500/ton in June 2016 , copper prices have risen over 57% up to $6,810/ton on 30 August due to strong Chinese demand and generally tightening fundamentals.

Bullish views on copper were recently con rmed in July when the metal broke above the $6,000 /ton leading to a new trading rang e between $6,000 - 7,000/ton that will prompt an upside revision to BMI Research's price forecast in the coming weeks.

While it is possible that prices may unwind from current levels towards the end of the year, BMI Research thinks the gradual uptrend over the last 12 months will bode well for mining activity in Zambia as copper producers will likely raise production on the back of increased pro tability.

"Zimbabwe's democracy has been undermined and it has led to serious human rights abuses," says Michael Gibb, who submitted the report for Global Witness.

Similar structures to those in Zimbabwe are also to be found in other big diamond countries in Africa. Diamond deposits have also led to more poverty, violence and oppression in Angola or the Democratic Republic of Congo.

Botswana: More transparency, more added value ings are different in Botswana. e biggest diamond producer in Africa is regarded as a model in many respects when it comes to channeling pro ts from the export of raw materials back into society. 75 percent of the country's foreign exchange revenue comes from the sale of rough diamonds.

Botswana seems to have learned from the negative examples in Africa. It tries to keep the value added chain in the country for as long as possible. A large quantity of the rough diamonds are processed – divided, cut, polished, drilled – in Botswana itself. Until just a few years ago, this was done in, for example, the Belgian city of Antwerp, or in Israel. is is still the case with other African diamond producers.

Using diamond money to improve the economy overall Unlike almost all the other countries in Africa, Botswana has dealt carefully with its riches. e government affords itself social programs that its African neighbors regard with envy. ese include free school education and free health

Gold mining in DRC, from the ore to the bar For the people in the eastern DRC, small-scale gold mining is a key source of income. e workers risk their lives digging for the ore, which passes through many hands before it becomes a gleaming bar of pure gold.

Back-breaking work Deep down, a miner in a rural artisanal gold mine chisels gold ore out of the earth. e sha team is composed mainly of excavators and bag porters.

Miners spend six to eight hours down the shas each day. e work is physically demanding. At this mine, around 200 kilograms of ore must be excavated to extract one gram of gold Sacks of rocks for a gram of gold A miner maneuvers through a narrow tunnel junction, as his colleague waits in line. e bags of ore he has been heaving through the mine, in the direction of the minesha entrance, are in front of him. Aer agriculture, artisanal mining is the most important livelihood in the eastern Democratic Republic of the Congo (DRC).

30 kilos per load A bag porter carries his load downhill from the mine for processing. e porters are paid 500 Congolese Francs - about $0.35 (0.29 Euros) at current Eastern Congo exchange rates - per bag by the sha managers, and can make up to several dollars per day. ey are among the lowest earners at the mine and, at this site, are oen those who have migrated from other areas.

Encased in the rock A man kneels in front of a rock slab while breaking down gold ore with a grinding stone. Next, the remaining ore is manually ground down between two rocks to release the gold. is is a slow and arduous process; one plastic basin can take several hours to work through. Water carriers and ore porters are visible moving up and down the mine hill, in the background.

First sales A local on-site trader assesses how much to offer for the gold a client has brought him. e gold and mercury compound seen in the trader's plastic dish is a dull metallic grey at this point in the treatment process. Many miners will look to sell these small gold quantities to on-site traders.

Re ning gold A 'big trader' heats the gold and nitric acid over a hot stove to rid it of any remaining impurities. Big traders deal in far larger quantities of gold than the local traders; they frequently trade more than several kilograms of gold in one week. eir pro t margins are smaller than the local traders, but they trade in greater volume, which assures them a much higher income.

Precious powder Aer heating, the gold is weighed on an

electric scale. At this stage, the gold has reached between 92 and 98 percent purity, depending on its origin.

Red-hot riches Once melted, the gold is cast in an ingot mould. Aer removing the red-hot crucible from the furnace, a worker at the gold smelter pours the molten gold into a graphite ingot mould for casting.

Inside the furnace, the gold reaches temperatures of 1,500 degrees Celsius.

An early user of the elemental analyser technology in minerals was an iron ore mining and processing operation in South Africa. e company used an overland conveyor to transfer crushed ore to the process plant. e quality of the ore was variable and a need to effectively monitor its composition in real time was identi ed to allow a consistent product quality to be achieved. e GEOSCAN analyser was installed in 2003. e plant was then able to respond to expected changes in ore quality before the ore arrived, and improved its

Jansen van Rensburg highlights that I-CAT ensures that no less than 2 000 litres of ambient air is discharged at a high velocity with every litre of water atomised with the system. “It is a critical ratio to achieve maximum percentage evaporation of water pumped into the air. is ensures the column of air does not become dense to the point which it resembles a sprinkler and guarantees the particles do not cluster together, forming a column of water which impacts aerial evaporation.” e I-VAP500, which is delivered within eight to 12 weeks, is offered in different scopes and options, depending on the site size. It boasts a high velocity air stream and has a large 3.2 mm ori ce water fracturing nozzle design to ensure minimal downtime from nozzle blockage, while achieving the nest possible droplet size.

I-CAT aims to introduce more of its evaporation solutions to the international market. “Our aim is to become the market leader in any services related to the environment and to be the 'port-o-call' for any such services to our clients.
