||PCT/PE2016/000004||PONTIFICIA UNIVERSIDAD CATÓLICA DEL PERÚ||PILLIHUAMÁN ZAMBRANO, Adolfo|
The invention relates to the hydrometallurgical process for the recovery of gold from arsenical refractory minerals, which promote a more efficient recovery in comparison to the conventional processes. This process comprises two steps: i) once the gold concentrate (arsenopyrite and arsenical pyrite) is obtained, same passes through a regrinding step, with the addition of the oxidising reagent, and subsequently through an intensive cyanidation step, with the addition of the dispersing reagent.
WO/2017/065622 METHOD FOR EXTRACTING METALS FROM CONCENTRATED SULPHURATED MINERALS CONTAINING METALS BY DIRECT REDUCTION WITH REGENERATION AND RECYCLING OF THE REDUCING AGENT, IRON, AND OF THE FLUX, SODIUM CARBONATE||WO||20.04.2017|
||PCT/PE2016/000014||CÁRDENAS ARBIETO, Francisco Javier||CÁRDENAS ARBIETO, Francisco Javier|
A method is disclosed for extracting metals from concentrated sulphurated minerals containing metals by direct reduction with regeneration and recycling of the reducing agent, iron, and of the flux, sodium carbonate. It is a combination of pyrometallurgical and hydrometallurgical processes which differ from the conventional processes. They do not require previous toasting of the concentrated sulphurated minerals and are technically and economically more advantageous than the presently used processes, since they directly reduce to zero the positive oxidation state of the metal, using a single reactor for extracting the metal, regenerating and recycling the metallurgical feed materials in complementary processes, the kinetics of the chemical reactions being characterised by high speed, without generating any slags or pollutant gases. The metals can be extracted at a reduced cost and in an environmentally sustainable manner.

WO/2017/007344 SELF-PROPELLED VEHICLE FOR DRILLING ROCK FOR SMALL-SCALE UNDERGROUND MINING, MOUNTED ON WHEELS AND HAVING AN ARTICULATED CHASSIS||WO||12.01.2017|
||PCT/PE2015/000011||RESEMIN S.A.||DIAZ LÓPEZ, Fernando|
In summary, the utility model according to the invention is applied to an original articulated drilling vehicle, which has two purposes. The first is to improve lateral stability of the vehicle when it turns, and the second is to have access to tunnels or galleries of restricted height, with the vehicle being very manoeuvrable and compact. The drilling vehicle carries out works to drill holes in underground mining. After having created the holes, the vehicle is removed from the area so that the mine personnel can place the dynamite and the blowing-up process is carried out in the area where dynamite was placed. Said activities can be for the purpose of extracting minerals or advancing the tunnel towards the mineral vein. The main characteristic of the invention is that is enables drilling works to be carried out in tunnels with narrow sections where, until now, self-propelled drilling vehicles could not enter. In these tunnels with narrow sections, the mineral extraction works are carried out artisanally or manually, and expose the personnel working on these operations to health risks.
