Examples of apparatuses for harvesting water are described herein. The apparatuses include a wall having a hydrophilic contacting surface and a hydrophobic collecting surface. A plurality of pores defining an inner volume extend between the contacting surface and the collecting surface and provide a fluid flow communication between the contacting surface and the collecting surface. As air is directed across or towards the wall, water condenses on the contacting surface, seeps into the pores and passes through the wall to the collecting surface for collection.

Methods and apparatuses for harvesting water from air

There are provided processes for preparing alumina. These processes can comprise leaching an aluminum-containing material with HCl so as to obtain a leachate comprising aluminum ions and a solid, and separating said solid from said leachate; reacting said leachate with HCl so as to obtain a liquid and a precipitate comprising said aluminum ions in the form of AlCl, and separating said precipitate from said liquid; and heating said precipitate under conditions effective for converting AlClinto AlOand optionally recovering gaseous HCl so-produced. These processes can also be used for preparing various other products such as hematite, MgO, silica and oxides of various metals, sulphates and chlorides of various metals, as well as rare earth elements, rare metals and aluminum.

Processes for preparing alumina and various other products

The present disclosure relates to processes for recovering rare earth elements from an aluminum-bearing material. The processes can comprise leaching the aluminum-bearing material with an acid so as to obtain a leachate comprising at least one aluminum ion, at least one iron ion, at least one rare earth element, and a solid, and separating the leachate from the solid. The processes can also comprise substantially selectively removing at least one of the at least one aluminum ion and the at least one iron ion from the leachate and optionally obtaining a precipitate. The processes can also comprise substantially selectively removing the at least one rare earth element from the leachate and/or the precipitate.

There are provided processes for treating red mud. For example, the processes can comprise leaching red mud with HCl so as to obtain a leachate comprising ions of a first metal (for example aluminum) and a solid, and separating said solid from said leachate. Several other metals can be extracted from the leachate (Fe, Ni, Co, Mg, rare earth elements, rare metals, etc.). Various other components can be extracted from solid such as TiO, SiOetc.

There are provided processes for purifying aluminum ions. Such processes comprise precipitating the aluminum ions under the form of Al(OH)at a first pH range; converting Al(OH)into AlClby reacting Al(OH)with HCl and precipitating said AlCl; and heating the AlClunder conditions effective for converting AlClinto AlOand optionally recovering gaseous HCl so-produced. The processes can also comprise converting alumina into aluminum.

The processes can also comprise substantially selectively removing the at least one rare earth element from the leachate and/or the precipitate.

Processes for recovering rare earth elements from various ores

The disclosed processes can be effective for treating various materials comprising several different metals. These materials can be leached with HCl for obtaining a leachate and a solid. Then, they can be separated from one another and a first metal can be isolated from the leachate. Then, a second metal can further be isolated from the leachate. The first and second metals can each be substantially selectively isolated from the leachate. This can be done by controlling the temperature of the leachate, adjusting pH, further reacting the leachate with HCl, etc. The metals that can be recovered in the form of metal chlorides can eventually be converted into the corresponding metal oxides, thereby allowing for recovering HCl. The various metals can be chosen from aluminum, iron, zinc, copper, gold, silver, molybdenum, cobalt, magnesium, lithium, manganese, nickel, palladium, platinum, thorium, phosphorus, uranium, titanium, rare earth element and rare metals.

Processes for preparing alumina and magnesium chloride by HCl leaching of various materials

There are provided processes for preparing various products from various materials. For example, such processes are effective for extracting titanium and various other metals from various materials, thereby allowing for preparing products such as titanium chloride and titanium oxide. These processes can comprise leaching the starting material with HCl so as to obtain a leachate and a solid. The solid can be treated so as to substantially selectively extract titanium therefrom while the leachate can be treated so as to substantially selectively recover a first metal chloride therefrom.

Processes for preparing titanium oxide and various other products

There are provided processes for treating fly ash. For example, the processes can comprise leaching fly ash with HCl so as to obtain a leachate comprising aluminum ions and a solid, and separating the solid from the leachate; reacting the leachate with HCl so as to obtain a liquid and a precipitate comprising the aluminum ions in the form of AlCl, and separating the precipitate from the liquid; and heating the precipitate under conditions effective for converting AlClinto AlOand optionally recovering gaseous HCl so-produced.

Processes for treating fly ashes

There are provided methods for separating iron ions from aluminum ions. For example, the methods can comprise providing a basic aqueous composition comprising said iron ions and said aluminum ions and having a pH of about 10.5 to about 13 and a temperature of about 50 &#xb0; C. to about 150 &#xb0; C.; reacting said basic aqueous composition with hematite so as to promote, catalyze and/or enhance formation of hematite and to obtain a liquid phase comprising said aluminum ions and a solid phase comprising said so-formed hematite generated with said iron ions; and separating said liquid phase from said solid phase.

Methods for separating iron ions from aluminum ions

There are provided processes for extracting aluminum ions from aluminous ores and for preparing alumina. Such processes can be used with various types of aluminous ores such as aluminous ores comprising, for example, various types of metals such as Fe, K, Mg, Na, Ca, Mn, Ba, Zn, Li, Sr, V, Ni, Cr, Pb, Cu, Co, Sb, As, B, Sn, Be, Mo, or mixtures thereof.
