Best way to melt nickel at home?
I have a small source of 99%+ pure nickel. I was wondering what would be the best way to melt it all together and keep its purity. economically too. As nickel has a high melting point approx 2651F. Would just melting with a tourch work. Or would I need a hotter source of heat. And also is there any other high nickel purity products.

Nickel Smelting and refining | Drive Sustainability
Sulphide ores are easier to process using conventional smelting and refining methods than laterite ores. For sulphide ores, nickel concentrates from the beneficiation stage are often smelted at high temperature (approximately 1,350°C) to produce an intermediate product called matte, which is a nickel-iron sulphide, usually containing 25-45% nickel.
