Production of the red metal plunged 20.4% in the first half of 2020. Part of the iodate in the solution is reduced to iodide using sulfur dioxide, which is produced by burning sulfur. SQM 18,12 mag/arcsec² (5,12 m) — leichte Wolken kamen auf SQM 21,95 mag/arcsec² Namibia 5 Uhr Morgens Lichtverschmutzung: Beispiele der iPhone-App “Dark Sky” Caliche ore overburden is removed with bulldozers. Caliche ore overburden is removed with bulldozers.

Caliche ore concentrations vary from one mine to the next.

After that, explosives are used to break the mineral into smaller pieces, which is then loaded onto trucks using front loaders. In 2016 Chile’s environmental regulator SMA found that SQM had extracted more brine from the salt flat than permitted. Their geological origin is not clear. In Pedro de Valdivia, trucks carry and pile the mineral in heaps near temporary railway stations, where it is loaded onto rail cars to be taken to the plant.

The production of lithium carbonate and lithium hydroxide starts with the lithium chloride solutions obtained from the Salar de Atacama as a byproduct of the production of potassium chloride. SQM has obtained patents in Chile and the United States for its iodine prilling process. In all, SQM extracts around 30 million tons of caliche ore each year. These solutions are then processed to obtain lithium carbonate and lithium hydroxide at a plant in the Salar del Carmen, close to Antofagasta. The solutions resulting from the process of leaching caliche ore at the plants in Pedro de Valdivia, María Elena and Nueva Victoria are used to produce iodine from the iodate contained in them. After that, explosives are used to break the mineral into smaller pieces, which is then loaded onto trucks using front loaders.

It is then transferred to a vat leaching plant where nitrate and iodine are extracted.

Antofagasta said that its operations at Los Pelambres, the closest large deposit to the epicenter, had not been affected.

It predicts that lithium will soon become its second-largest mining asset, behind copper.

SQM’s access to vast nitrate and lithium reserves in northern Chile is expected to attract a number of suitors. We have the technological development and proven experience to carry out highly efficient production processes in each of our business lines.The caliche ore deposits located in northern Chile are the largest ever discovered and the only source of commercially exploitable natural nitrates in the world. In all, SQM extracts around 30 million tons of caliche ore each year.

Da SQM von der langfristigen Produktionsausweitung profitiert, könnte die Aktie langfristig interessant sein. The commodity is currently SQM’s own expansion plans are on track to be completed by the end of 2021, the company said.Brine pools and processing areas at SQM’s lithium mine on the Atacama salt flat.

( At the plants, caliche ore is mechanically ground until it reaches approximately half an inch in size. The solutions from leaching caliche ore contain iodine in the form of iodate.

The Santiago-based miner saw net income fall to $50.8 million, a 27.6% drop when compared to the same period last year.“We believe that prices will be lower during the second half of the year compared to the prices observed in the first half of the year, although sales volumes should be higher,” chief executive Ricardo Ramos said in SQM produces lithium by pumping brine from beneath the Atacama desert, the world’s driest, which it concentrates through evaporation in pools.

The map uses NOAA/EOG VIIRS, World Atlas 2015, observatories, clouds and SQM/SQC overlay contributed by users. The resulting iodide is combined with the rest of the original iodate solution to release the elemental iodine. It is thought that the caliche ore formed from sediment deposits from an ancient inland sea or the accumulation of minerals as the result of erosion of the western face of the Andes Mountains. Then, the solid iodine is refined using a melting and prilling process. At María Elena, Nueva Victoria and Pampa Blanca (located in Sierra Gorda), the mineral is heap leached to obtain solutions to be used for iodine production. The amount of land used for mining has more than tripled since March last year.

Chile’s SQM (NYSE: SQM), the world’s second largest lithium producer, The company said it is now producing at record levels of roughly 70,000 tonnes for the year, which has allowed it to build higher levels of inventory ahead of an expected demand boom.“Given the demand growth expectations in coming years, we feel comfortable with the higher level of inventories that are being built,” it said.SQM is producing at record levels of roughly 70,000 tonnes for the yearSQM also sold more lithium in the three months to June 30 than in the first quarter, delivering 12,600 tonnes of the white metal, up 45% from the January-March period.Weak lithium prices, however, impacted SQM’s bottom line.

It is then transported to solar evaporation ponds where salts with high nitrate concentrations crystallize and are subsequently transported by truck to the Coya Sur plants to be used as an input to produce potassium nitrate. Variations in iodine content and other chemical components of the treated mineral, as well as other operational parameters, require a high level of specific knowledge to efficiently manage the process.

Caliche ore can be found beneath a blanket of inert material between 0.5 and 2.5 meters thick, in layers from 0.2 to 5 meters thick.
