Inca One to launch online bullion store



Canada’s Inca One Gold (TSXV: IO) announced that it will launch an online bullion store so that collectors and investors can purchase gold directly from the company. 

In a press release, the gold producer said its bullion store will initially offer 1-ounce gold coins and will add additional products, including silver options in the future. The inaugural Peruvian-themed coins will be stamped and minted by Inca One.

“Upon the onset of the global pandemic, Inca One recognized the immediate need for precious metal investors to purchase gold and silver bullion. As a result, the company views this as an ideal opportunity to begin selling its gold and silver directly to the retail bullion investor,” the media brief states.

“We will be offering bullion from Peruvian small-scale miners who have had their ore processed at one of our facilities.”

Inca One operates two, fully-permitted, gold ore processing facilities in the Arequipa region of southwestern Peru. Chala One is a mineral processing facility with a permitted capacity of 100 tonnes per day, and Kori One is a gold ore processing facility featuring a carbon-in-leach gold circuit, with a maximum permitted capacity of 350 tonnes per day.

Ball Mill Liner Material Selection

Different crushed material, different working conditions need different material liners to suit. Also, the coarse grinding compartment and fine grinding compartment need different material liners.

H&G Machinery supplies the following material to cast your ball mill liner:


Manganese Steel

The manganese content of the high manganese steel ball mill lining plate is generally 11-14%, and the carbon content is generally 0.90-1.50%, most of which are above 1.0%. At low impact loads, the hardness can reach HB300-400. At high impact loads, the hardness can reach HB500-800. Depending on the impact load, the depth of the hardened layer can reach 10-20mm. The hardened layer with high hardness can resist impact and reduce abrasive wear. High manganese steel has excellent anti-wear performance under the condition of strong impact abrasive wear, so it is often used in wear-resistant parts of mining, construction materials, thermal power, and other mechanical equipment. Under the conditions of low impact conditions, high manganese steel cannot exert the characteristics of the material because the work hardening effect is not obvious.

Chrome Alloy Steel

Chromium alloy cast iron is divided into high chromium alloy cast iron (chromium content 8-26% carbon content 2.0-3.6%), medium chromium alloy cast iron (chromium content 4-6%, carbon content 2.0-3.2%), low chromium Three types of alloy cast iron (chromium content 1-3%, carbon content 2.1-3.6%). Its remarkable feature is that the microhardness of M7C3 eutectic carbide is HV1300-1800, which is distributed in the form of a broken network and isolated on the martensite (the hardest structure in the metal matrix) matrix, reducing the cleavage effect on the matrix. Therefore, the high-chromium alloy liner has high strength, ball mill toughness, and high wear resistance, and its performance represents the highest level of current metal wear-resistant materials.
