Liberia was a major exporter of iron ore on the world market. in the 1970s and 1980s, iron mining accounted for more than half of liberia's export earnings. since the coup d'etat of 1980, the country's economic growth rate has slowed down because of a decline in the demand for iron ore on the world market and political upheavals in liberia.

Liberia’s climate is tropical hot-humid. winters are dry with hot days and cool to cold nights; summers are wet and cloudy with frequent heavy showers. the rainy season lasts from april to november and average annual rainfall is estimated at 2 391 mm, with a spatial variation from 2 000 to 5 000 mm.

Garnet is a weak magnetic mineral with high hardness and chemical stability. it is mainly used in abrasives, building materials and polymer fillers. the garnet ore grade is not high, and the industrial-grade requirement is more than 14%. it is the basis of deep processing of garnet by magnetic separation and gravity to increase the garnet grade.

Garnet – there are 15 garnet species found a wide range of colors, although it is commonly available in dark red hues. garnet is the birthstone for january. garnet is the birthstone for january. labradorite – named after the location of its discovery (labrador, canada), the crystal formation of the stone creates the “schiller” effect ...

In situ leach (isl) mining. isl mining has environmental and safety advantages over conventional mining in that the ore body is dissolved and then pumped out, leaving minimal surface disturbance and no tailings or waste rock (world nuclear association, 2012).

The wet solids are transferred to agitation tanks where air is added. the oxygen sets off a chemical reaction between the gold and the cyanide trapped in the ore, triggering the gold to dissolve and leach into the surrounding water. drum filters then separate the water from the solids. zinc powder is then added to solidify the dissolved gold.

The majority of garnet mining is for massive garnet that is crushed and used to make abrasives. garnet is a silicate mineral group; in other words, garnet’s complex chemical formula includes the silicate molecule (sio 4). the different varieties of garnet have different metal ions, such as iron, aluminum, magnesium and chromium.

It is divided into dry type and wet type magnetic machine. the weak magnetic ore mainly has limonite, hematite, manganese ore, and symbiotic ore (multiple ores coexisting). these weak magnetic ores are mainly composed of ferric oxide, if you want to extract ferric oxide, you need to use high-strength magnetic equipment.
